I submit that impact of solid bodies is the most fundamental of all interstellar processes that have taken place on the terrestrial planets: without impact, Earth, Mars, Venus, and Mercury would not exist.

Simply put, the collision of smaller objects is the process by which the terrestrial planets were born. On the surface, that the geological record of the earliest history of impacts on the terrestrial planets has been lost, is troubling. As the process is self-erasing, to a certain extent, the earliest record would have been lost even if processes of melting and internal evolution of the planets had not occurred. But much of the record of the last stages of accretion of the planets is preserved, especially on the moon, Mercury, and Mars. In fact, the last stage of accretion is still going on, albeit at a very slow rate.

This is fortunate, because we can study many aspects of the processes of planetary birth by investigation of the nature of small bodies that still exist, the dynamics of their orbital evolution, and the effects that they produce when they ultimately collide with a planet. If impact and accretion were not still occurring, it would be hard to come to grips with a number of difficult problems of planetary origin and early evolution.

1. The primary purpose of the passage is to

A. present evidence that argues against a common misconception in the formation of planets
B. undermine a claim regarding the role accretion plays in planetary evolution
C. argue for the importance of using existing planetary conditions to understand prior cosmic occurrences
D. underscore the importance of an astronomical process and describe ways in which we can understand this process
E. discuss how, unless immediate action is taken, astronomers will squander an opportunity to better understand planetary formation



2. It can be most reasonably inferred that which of the following accounts for the lack of a geological record concerning the history of impacts on the planets?

A. the violence of the initial impact
B. an outcome that is not self-erasing
C. a process of change in planets themselves
D. the absence of proof relating to a hypothetical collision
E. the ongoing process of accretion



3. The author suggests that at least some of “a number of difficult problems...”can be understood by

A. extrapolating from observable phenomenon
B. anticipating the result of the collision of small bodies
C. studying the rate of accretion on planets
D. observing the internal process of planets
E. discounting the dynamics of how orbits change over time

It seems like author is presenting a scientific paper about his views on a theory. The first para gives a theory

Second para says why no proof exist and further where proof can be found.

Third para explains why it are the advantages of studying the current examples to get idea about the old stuff.

1) D is the only one that covers the scope of all the 3 paragraph. Secondly, observe the author never argues for proving his point. The tone is not arguing.

2) As the process is self-erasing, to a certain extent, the earliest record would have been lost even if processes of melting and internal evolution of the planets had not occurred.

That means these processes were responsible for lost records. Evolution of planets means change in the planet.

3) If impact and accretion were not still occurring, it would be hard to come to grips with a number of difficult problems of planetary origin and early evolution

What author means is we can observe the current phenomena to understand the past phenomena. It is kind of extrapolating from the present data.

Hi sumit411,

Hey Sreyoshi,

If impact and accretion were not still occurring---> we are concerned by accretion and not RATE of accretion.

Hope this helps.

Hey csaluja

Notice this in the paragraph :As the process is self-erasing---> it means the process was self erasing ( such as melting of ice and evolution of plants). B says the opposite.

Hope this helps.

Hi,

But even if the process is self-erasing, whatever the outcome comes out and if that is not self-erasing, can we still not predict why the earliest record were lost? Option C makes sense but I am still confused regarding option B.

Hi ,
Can anyone help me with Q2.
For what i understand is why there is lack of geographical record?
lack of geographical record is due to process that is self erasing.
Even if processes of melting and internal evolution of the planets had not occurred, there is still lack of geographical record.
So from my point of view , both A and C should be wrong. Can someone help me with this?

Correct. The question asks for the reasons for the lack of a geological record.

Self-erasing is the reason to a certain extent. it is not the sole reason. Observer the following line from the passage.

As the process is self-erasing, to a certain extent

The remaining extent for the loss of the geographical records is the "processes of melting and internal evolution of the planets". Option C correctly conveys this meaning by saying "a process of change in the planets themselves".

Hence option C is correct.

Official Explanation for Q1



Answer: (D)

The purpose of the passage is to discuss the importance, for those wanting to learn more about the evolution of our planets, of the “impact of small bodies.” The passage specifically advocates using current processes to understand the historic processes.

(A) is wrong because there is no “common misconception” mentioned.

(B) is incorrect because accretion plays an important role

(C) is tempting because the passage does mention this. But the primary purpose is not only to discuss the importance of extrapolation but to assert the importance of the “impact of solid bodies” on the formation of our solar system.

(E) There is no talk in the passage about scientists potentially missing out on an opportunity.

Official Explanation for Q3



Answer: (A)

The sentence, “This is fortunate…” describes how scientists can observe current events taking place in or regarding planets to learn more about “difficult problems of planetary origin…”.

(A) supports this idea best. ‘Extrapolating’ means taking information from one instance and applying it to an unknown instance (in this case, the early evolution of planets).

(C) is a tempting answer. But scientists are relying on a host of planetary occurrences (“the dynamics of their orbital evolution, and the effect...”). While accretion is mentioned as an important process currently taking place, it doesn’t explicitly say the rate of accretion is key to understanding “a number of difficult problems.”

Official Explanation for Q2



Answer: (C)

The passage mentions that “the geological record…has been lost.” In the following sentence, it mentions that “melting and internal evolution” can erase the early geological history of a planet. Therefore, we can infer that a process within the planet themselves can erase the geological record. Answer: (C).

(A) is incorrect because nowhere does it mention the violence of any initial impact.

(B) is the opposite of what we are looking for. The processes that do not leave any record of the geological history are self-erasing.

(D) is incorrect since the passage does not talk about this hypothetical collision.

While accretion is still occurring, it does not account for why there is no geological record of the history of planet. Thus (E) is wrong.
