[1] In the
southeastern Pacific Ocean, on the piece of land known as Easter Island (now a
territory of Chile), stand several hundred massive stone monoliths. These
carvings, called “moai,” are recognizable by their oversized heads, with their
heavy brows, long noses, elongated ears, and protruding lips. While they
average four meters in height and 12.5 tonnes, the largest is almost 10 meters
tall and the heaviest weighs a full 86 tons. The upright sculptures are
scattered around Easter Island, many installed on platforms called “ahu” along
the coast, while others are more inland and several stand near the main
volcanic quarry of Rano Raraku. The Rapa Nui people of the island built a total
of 887 of these impressive statues between the 12th and 16th centuries. They
were, it is said, symbols of religious and political authority, embodiments of
powerful chiefs or ancestors which faced inland toward the island’s villages,
perhaps watching over their creators, keeping them safe.
[2] While
the very creation of such monoliths – most out of volcanic ash with stone hand
chisels – is an impressive feat, what is more remarkable (not to mention
mysterious) is how they were transported to their resting places. In
the past, most researchers associated the building and transportation of the
moai with widespread deforestation on the island and eventual collapse of the
Rapa Nui civilization. This hypothesis is based, in part, on the fact that the
pollen record suddenly disappears at the same time as the Rapa Nui people
stopped constructing the moai and transporting them with the help of wooden
logs. How exactly would logs facilitate the movement of the statues? Most
proponents of this method believe that the people created “rollers” by
arranging parallel logs on which the prone statues were pulled, or
pushed. They would not have required an entire roadway
of logs, since logs from the back could be placed at the front, creating a
moving platform of sorts. To make it easier to roll, and keep in position, the
statue would be placed on two logs arranged in a V shape.
[3] One
proponent of this idea of rolling the statues in a prone position is Jo Anne
Van Tilburg, of UCLA. Van Tilburg created sophisticated computer models that
took into account available materials, routes, rock, and manpower, even
factoring in how much the workers would have to have eaten. Her models
supported the idea that rolling prone statues was the most efficient method. As
further evidence, Van Tilburg oversaw the movement of a moai replica by the
method she had proposed. They were successful, but evidence that it was
possible is not necessarily evidence that it actually happened.
[4] Van Tilburg
was not the only one to have experimented with rolling the statues. In the
1980s, archaeologist Charles Love experimented with rolling the moai in an
upright position, rather than prone, on two wooden runners. Indeed, a team of
just 25 men was able to move the statue a distance of 150 feet in a mere two
minutes. However, the route from the stone quarries where the statues were
built to the coast where they were installed was often uneven, and Love’s
experiments were hampered by the tendency of the
statues to tip over. While Love’s ideas were dismissed by many, the idea of the
statutes tipping over along the route was consistent with the many moai found
on their sides or faces beside the island’s ancient roads. And local legend
held that the statues “walked” to their destinations, which would seem to
support an upright mode of transportation. In fact, rolling was not the only
possible way of transporting the moai in an upright position.
[5] In the
1980s, Pavel Pavel and Thor Heyerdahl had experimented with swiveling the
statues forward. With one rope tied around the head and another around the
base, they were able to move a five-ton moai with only eight people, and a
nine-ton statue with 16. However, they abandoned their efforts when their
technique proved too damaging; as they shuffled the statues forward, the bases
were chipped away. This confounding factor led most to believe that an upright,
rope-assisted walking method was incorrect.
[6] But many
now believe that they were, in fact, transported upright. In 2012, Carl Lipo of
California State University Long Beach and Terry Hunt of the University of
Hawaii teamed up with archaeologist Sergio Rapu to refine the upright walking
idea. They found that the statues that appeared to be abandoned in
transit had bases with a curved front edge. This meant they would naturally
topple forward and would need to be modified once they reached their
destinations. But that curved edge also meant that they could easily be rocked
forward using a small team of people and three ropes attached to the head.
Indeed, their experiments demonstrated the feasibility of this method, and
their theory has gained traction.

leave out essential information.
While the very
creation of such monoliths – most out of volcanic ash with stone hand chisels –
is an impressive feat, what is more remarkable (not to mention mysterious) is
how they were transported to their resting places.
- The transportation of the moai is
both remarkable and mysterious, but not as impressive as the actual
creation of the statutes.
- The moai were carved with stone
hand chisels, which is an impressive accomplishment, but it is still
unknown whether the people actually transported them.
- The creation of the moai is amazing,
but not as amazing as how they were transported.
- The transportation of the moai is
remarkable, mysterious, and as impressive as their creation with simple

The highlighted
sentence shows a contrast, or difference between two ideas, introduced with the
contrast word “while.” The sentence also indicates a comparison, as shown by
“what is more remarkable.” To choose the correct sentence, which may lack all
the detail of the original, we must get the relationship correct between the
two ideas: the first is that the creation of the moai is impressive; the second
is that the transportation of the moai is more impressive.
(A) is incorrect because it has the comparison backwards, saying that the
transportation is “not as impressive as” the creation.
(B) is incorrect. Although the answer includes the word “but,” which shows a
contrast between ideas, it only states that it is “unknown” whether the statues
were transported rather than saying it is more impressive than their creation.
(C) is correct. This answer correctly conveys the two basic ideas with the
correct comparison and the contrast word “but.”
(D) is incorrect because it says the transportation was “as impressive as” the
creation, which means they were equally impressive.
2 In
paragraph 2, what does the author say about past theories of how the moai were
transported from quarries to their resting places?
- The theories claimed that that use
of natural resources for transporting moai had devastating effects on the
land and society.
- The theories relied on evidence of
log roadways that remained long after the Rapa Nui people had disappeared.
- The theories were supported by oral
accounts of the use of wood by the Rapa Nui peoples at the time the moai
were constructed and transported.
- The theories were based on
inaccurate estimates of the amount of wood required to transport moai over
long distances.

Correct Answer:
a
Your Selection: Not Answered
To understand
the “past theories” about moai transportation, we must read the entire
paragraph. We can see “in the past, most researchers,” which indicates the
sentence is about past theories. And we also see “this hypothesis” and
“proponents of this method,” both of which are about the “past theories.”
(A) is correct, since the passage tells us that researchers “associated the
building and transportation of the moai with widespread deforestation on the
island and eventual collapse of the Rapa Nui civilization.” That means that the
natural resources – wood – were completed used up (deforestation), and the
collapse of the civilization is clearly a “devastating effect.”
(B) is incorrect. The idea of log roadways is described, but this is pure
speculation. Although the log arrangement is described in some detail, we are
not told that actual log roadways still exist.
(C) is incorrect because no “oral accounts,” which means spoken history, are
mentioned in the paragraph.
(D) is incorrect. Although the amount of wood or logs is briefly discussed, the
estimates are not shown to be inaccurate.

'they' in paragraph 2 refers to:

Correct Answer:

Your Selection: Not Answered
To answer this
question, we must think about who or what “required an entire roadway of logs.”
Note that “would not have required” is in the past.
(A) is incorrect. It is not the “proponents” or supporters of the theory that
required logs. We are looking for something from the past.
(B) is correct. The sentence before says that “people created rollers,” and
this sentence is saying “they would not have required” something. The focus is
on what people did and needed.
(C) is incorrect. The rollers are the roadway of logs, so the rollers can’t
require an entire roadway.
(D) is also incorrect because the focus is on what people did, so it is logical
to say that the people did not require an entire roadway.
4 Why does
the author mention “sophisticated computer models” developed by Jo Anne Van
Tilburg in paragraph 3?
- to emphasize the difficulty of
theorizing about the activities of people in the remote past
- to demonstrate that Van Tilburg’s
hypothesis appeared to be supported by evidence
- to cast doubt on theories that
relied more on experimentation than on effective digital modelling
- to show how archaeology can apply
modern tools to ancient mysteries

“Sophisticated
computer models” are mentioned near the start of this paragraph. We read about
what the models included before coming to the third sentence, which provides a
clue to this question:
Her models supported the idea that rolling the statues was the most efficient,
and probable, method.
Remember when answering a purpose question to keep in mind the purpose of the
entire paragraph, and the entire passage. In this case, the passage is all
about different theories of the transportation of moai, and the evidence behind
those theories.
(A) is incorrect. It is true that theorizing is difficult, but that is not why
the author mentions sophisticated computer models.
(B) is correct. The entire idea of computer modelling lends credence, support,
or believability to Van Tilburg’s theory.
(C) is incorrect. There is no direct comparison here between theories based on
experimentation and those based on digital modelling. In fact, Van Tilburg used
both in her research.
(D) is incorrect because it doesn’t fit with the overall purpose of the
paragraph and passage; the author’s point is not generally about tools we use
to understand the past, but about specific theories about one particular
activity in the past.

The sentence we
need to insert includes the phrase “her data.” It says that the data
demonstrates something very specific. So we can expect that before this
sentence we read more generally about her research. More particularly, we
should read about some research that produces data.
(A) is incorrect because before this spot there is no mention of any research,
so the inserted sentence appears to lack enough context.
(B) is correct. This comes after the general idea about her model supporting
the rolling statues idea. This inserted sentence then gives us more specific
information about that supporting evidence.
(C) and (D) are incorrect. These points come after the author introduces Van
Tilburg’s experiments with moving moai replica, which doesn’t generate “data”
like her computer models did.
6 In paragraph
3, what does the author NOT suggest about Jo Anne Van Tilburg’s hypothesis
concerning the method of transporting the moai?
- The use of computer modelling
provides evidence that rolling statues on logs would have been a very
efficient method of transportation.
- It was supported by successful
attempts at replicating how the Rapa Nui people may have rolled the
statues on logs.
- It provides conclusive evidence
that the Rapa Nui people used log-rolling techniques to move the moai.
- With all the variables taken into
account, there still wasn't enough to provide reasonable justification for
the log-rolling method.

Your Selection: Not Answered
To answer a NOT
question, we must eliminate the answer choices that are correctly represented
in the passage and find the statement that is not supported by the passage. In
this case, we must read all of paragraph 3 to find the various ideas related to
Van Tilburg’s hypothesis. It is a mistake to read only a portion of the
paragraph.
(A) is incorrect because the passage clearly states that “her models supported
the idea that rolling the statues was the most efficient method.” In this case,
“her models” refers to computer models stated in the sentence before.
(B) is incorrect. The last two sentences of the paragraph describe how Van
Tilburg successfully replicated the method, presenting this as “further
evidence.”
(C) is correct. The paragraph does not say that there is “conclusive evidence”
(which means clear proof) that Van Tillburg was correct. The final sentence
suggests that her research shows only that it is “possible,” but it doesn’t
show that it is certain.
(D) is incorrect. The author mentions several variables, but still there isn't
enough evidence to be conclusive.
7 What can
be inferred from paragraph 6 about the statues found at their eventual resting
places?
- They showed signs of having been
tipped over on their sides at some point in transit.
- The people intended for them to be
located elsewhere but were constrained by their transportation methods.
- Many were, in fact, created where
they were installed rather than at the quarries that were originally
assumed to be the place of creation.
- They did not have curved front
edges.

This is an
inference question, which means the correct answer is not stated directly in
the paragraph. Instead, we must interpret the given information and draw a
correct conclusion. Be careful not to assume too much, and you must be able to
point to evidence for your answer somewhere in the passage.
(A) is incorrect. While previous research resulted in the tipping of statues,
nothing is said or suggested in this paragraph that the statues tipped at some
point while being transported.
(B) is incorrect. You might be fooled or distracted by the word “abandoned,”
and think that people wanted the statues to be elsewhere, but this isn’t the
case.
(C) is incorrect. There is no evidence to suggest that the sculptures were not
transported.
(D) is correct. The paragraph explains that the curved front edge facilitated
the transportation of the statues, and also mentions that the statues “would
need to be modified once they reached their destinations.” Because a curved
front edge would make them tip forward, we can assume that to stand upright
freely in their final destinations, they would have to be modified so they
didn’t have a curved front edge.

Correct Answer:
c
Your Selection: Not Answered
In this
sentence, we read about statues “abandoned” in transit, which means when they
were being transported. This idea refers back to paragraph 4, when we learned
that many moai were found on their sides or faces beside the island’s ancient
roads. We also learn that “this meant they would naturally topple forward.” So,
what happens when the statues topple forward, or fall, while being transported?
(A) is incorrect. The research being discussed improves on the previous
research because the previous research damaged the moai. But in this research
damage is not discussed.
(B) is incorrect. They were abandoned because they tipped.
(C) is correct. “Abandoned” means something is left behind. This is what the
people did to the statues that had curved front edges that toppled over on the
way to their destinations.
(D) is incorrect. The statues were not altered in transit, but only once they
had reached their destinations.
9 Which of
the following methods of transportation does the author say is supported by the
most compelling evidence?
- The rolling of moai in an upright
position on logs.
- The shuffling of moai with ropes

(A) is incorrect. This is the method used by Charles Love, which is said to
have been “dismissed by many.”
(B) is incorrect. This is the method used by Pavel Pavel and Thor Heyerdahl,
which is not supported by evidence because of the damage done.
(C) is incorrect. This is the method used by Van Tillburg, which does have
evidence, but it doesn’t have the most compelling evidence.
(D) is correct. This method, described in paragraph 6, is introduced with “But
