This passage was excerpted from material published in 1996.

When a large body strikes a planet or moon, material is ejected, thereby creating a hole in the planet and a local deficit of mass. This deficit shows up as a gravity anomaly: the removal of material that has been ejected to make the hole results in an area in slightly lower gravity than surrounding areas. One would therefore expect that all of the large multi-ring impact basins on the surface of earth's moon would show such negative gravity anomalies, since they are, essentially, large holes in lunar surface. Yet data collected in 1994 by the Clementine spacecraft show that many of these Clementine basins have no anomalously low gravity and some even have anomalously high gravity. Scientists speculate that early in lunar history, when large impactors struck the moon's surface, causing millions of cubic kilometers of crustal debris to be ejected, denser material from the moon's mantle rose up beneath the impactors almost immediately, compensating for the ejected material and thus leaving no gravity anomaly in the resulting basin. Later, however, as moon grew cooler and less elastic, rebound from large impactors would have been only partial and incomplete. Thus today such gravitational compensation probably would not occur: the outer layer of moon is too cold and stiff.


1. According to the passage, the gravitational compensation referred to in the highlighted text is caused by which of the following?

(A) A deficit of mass resulting from the creation of hole in lunar surface
(B) The presence of material from the impactor in the debris created by its impact
(C) The gradual cooling and stiffening of the Moon's outer surface
(D) The ejection of massive amounts of debris from the moon's crust
(E) The rapid upwelling of material from the lunar mantle




2. The passage suggests that if the scientists mentioned in the highlighted text are correct in their speculations, the large multi-ring impact basins on the Moon with the most significant negative gravity anomalies probably

(A) were not formed early in the Moon's history
(B) were not formed by the massive ejection of crustal debris
(C) are closely surrounded by other impact basins with anomalously low gravity
(D) were created by the impact of multiple large impactors
(E) were formed when the moon was relatively elastic




3. The passage is primarily concerned with

(A) analyzing data from a 1994 exploration of lunar surface
(B) reconciling two opposing theories about the origin of lunar impact basins
(C) presenting a possible explanation of a puzzling finding about lunar impact basins
(D) discussing how impact basins on the Moon's surface are formed
(E) examining the claim that the moon's impact basins show negative gravity anomalies




Kindly provide explanations for 3rd Question. I selected E.

Hey!
Passages like these are tricky because they are so full of details that keeping track of the main idea can become disorienting.
And if you rely on memory of the passage from the first phase of reading alone - while answering the questions, chances are that you will probably pick some option that "sounds good" or "looks good" rather than the option that IS substantiated by the passage!

Let's look at the passage and see what parts were important and needed focus

When a large body strikes a planet or moon, material is ejected, thereby creating a hole in the planet and a local deficit of mass. This deficit shows up as a gravity anomaly: the removal of material that has been ejected to make the hole results in an area in slightly lower gravity than surrounding areas. One would therefore expect that all of the large multi-ring impact basins on the surface of earth's moon would show such negative gravity anomalies, since they are, essentially, large holes in lunar surface. Yet data collected in 1994 by the Clemenstine spacecraft show that many of these Clementine basins have no anomalously low gravity and some even have anomalously high gravity. Scientists speculate that early in lunar history, when large impactors struck the moon's surface, causing millions of cubic kilometers of crustal debris to be ejected, denser material from the moon's mantle rose up beneath the impactors almost immediately, compensating for the ejected material and thus leaving no gravity anomaly in the resulting basin. Later, however, as moon grew cooler and less elastic, rebound from large impactors would have been only partial and incomplete. Thus today such gravitational compensation probably would not occur: the outer layer of moon is too cold and stiff.

The passage talks about a phenomenon ; shows an example where this does not hold good - and gives explanation for that.
That's pretty much all the passage is concerned about

Hello idinuv,
The passage starts by discussing how impacted bodies in space show gravitational anomalies.
It then discusses the moon and its many craters - it then delves into explaining WHY the moon does not exhibit these negative anomalies.

Option C is correct as the passage does provide possible explanation of a puzzling finding about lunar impact basins (puzzling because the moon has lot of impacted areas, which should ideally show negative gravity anomalies, yet does not show any negative lunar anomalies)

Option E is wrong since the Moon DOES NOT show negative gravity anomalies.

Hope that clarifies things!

The Scope for Question 1 rests here " Scientists speculate that early in lunar history, when large impactors struck the moon's surface, causing millions of cubic kilometers of crustal debris to be ejected...."
This says that huge amounts of dense debris is ejected upwards. Option E is therefore correct.

Question 2
From the information (scientist's speculation) in the passage we know that if large impacts happened in the early stages, the impact areas would have quickly been covered with mass ejected from the mantle. Therefore the inference that can be made is that these ring shaped craters were formed much later.
Therefore Option A is correct.
Hope that helps,

Since I marked answer option for Q3 wrong , I want to discuss it.

I marked (C) and in my opinion it is wrong because of the words 'origin of lunar impact basins', when the author is concentrated on the gravity of the holes created in the impact and not the origin.

Please correct me if I am wrong.

1. According to the passage, the gravitational compensation referred to in the highlighted text is caused by which of the following?
A) A deficit of mass resulting from the creation of hole in lunar surface
E) The rapid upwelling of material from the lunar mantle

IMO: Upwelling of the material itself is gravitational compensation. So what caused this is because of deficit of mass.
hole caused deficit -> deficit caused upwelling -> upwelling of material (Gravitational compensation)
Please explain in detail.

Hello Steinbeck,
From the passage: "when large impactors struck the moon's surface, causing millions of cubic kilometers of crustal debris to be ejected, denser material from the moon's mantle rose up beneath the impactors almost immediately, compensating for the ejected material and thus leaving no gravity anomaly in the resulting basin."

Gravitational compensation refers to the above mentioned phenomenon.

Later, however, as moon grew cooler and less elastic, rebound from large impactors would have been only partial and incomplete. Thus today such gravitational compensation probably would not occur: the outer layer of moon is too cold and stiff.

So over a period of time rebounds from the Moon's surface ,did not cause huge debris to be ejected. Consequently ,denser material did not rose from the crust.

Look at the Options .Only Option E refers to it .

If you come across a dense passage ,avoid the technical jargon as much as possible. Focus more on the author's intent .Look at the question first and then read the passage .
Answering the question will be easier

These passages are very hard with the time constraint. For detail inference questions, if you look too much before the highlighted sections then you may be over thinking however in other cases that is not the case. Purpose questions for technical passages such as this one is not necessary hard, but the detailed questions are really tricky. Sometimes you just have to take an educated guess and move on. These passages also takes a huge mental drain as well.

Can you explain using POE why option A is answer to Q2 (scientists speculate).


I can help you on this question.
Ok let's refer to our passage.

When a large body strikes a planet or moon, material is ejected, thereby creating a hole in the planet and a local deficit of mass. This deficit shows up as a gravity anomaly: the removal of material that has been ejected to make the hole results in an area in slightly lower gravity than surrounding areas. One would therefore expect that all of the large multi-ring impact basins on the surface of earth's moon would show such negative gravity anomalies, since they are, essentially, large holes in lunar surface. Yet data collected in 1994 by the Clementine spacecraft show that many of these Clementine basins have no anomalously low gravity and some even have anomalously high gravity. Scientists speculate that early in lunar history, when large impactors struck the moon's surface, causing millions of cubic kilometers of crustal debris to be ejected, denser material from the moon's mantle rose up beneath the impactors almost immediately, compensating for the ejected material and thus leaving no gravity anomaly in the resulting basin. Later, however, as moon grew cooler and less elastic, rebound from large impactors would have been only partial and incomplete. Thus today such gravitational compensation probably would not occur: the outer layer of moon is too cold and stiff.

From Q2 The passage suggests that if the scientists mentioned in the highlighted text are correct in their speculations, the large multi-ring impact basins on the Moon with the most significant negative gravity anomalies probably?

So these scientists mentioned that in early time of the moon, when there is anything hit the moon really hard that that hit area should show gravity anomaly. But the moon was still elastic and its mantle rose up to compensate the gravity anomaly ---> No more gravity anomaly
If you keep reading the next sentence you will find that "Later, however, as moon grew cooler and less elastic, rebound from large impactors would have been only partial and incomplete."
From these sentences, you can make a guess without reading any answer choices that these whatever basins caused negative gravity anomalies ---> No compensation effect ---> Must occured when there was no compensation thing
That's how I got my answer "A"

Or if you wanna to use POE, we can take a look at each answer choices
(A) were not formed early in the Moon's history ---> Sound good. keep it.
(B) were not formed by the massive ejection of crustal debris ---> I look back to the passage and don't think this is really relevant. Out
(C) are closely surrounded by other impact basins with anomalously low gravity ---> the passage doesn't mention that gravity will be affected by surrounded basins. Out
(D) were created by the impact of multiple large impactors ---> Idk can't find any reference in the passage. Out
(E) were formed when the moon was relatively elastic ---> opposite to what are we looking for! Out

With POE. Answer is also "A" but this approach takes longer time.
