1. Astronomers have uncovered evidence that a star that was as bright as the full moon exploding into view 340,000 years ago, emitting dazzling radiation that could have disrupted Earth's protective ozone layer and sunburned our Stone Age ancestors.

A. that a star that was as bright as the full moon exploding into view 340,000 years ago, emitting -- verb is missing -- exploding is modifying moon.
B. that a star as bright as the full moon exploded into view 340,000 years ago, emitting -- subject verb matching -- ing modifier is used correctly.
C. of a star that was as bright as the full moon exploding into view 340,000 years ago and that it emitted -- evidence of a star -- star is not the intended object of preposition. -- exploding is modifying moon -- ing modifier cant be parallel to restrictive clause "that it..."
D. of a star as bright as the full moon, exploding into view 340,000 years ago and emitting -- same as C -- -ing modifier exploding and emitting is modifying Astronomers.
E. of a star as bright as the full moon that exploded into view 340,000 years ago and that emitted -- same as C -- that modifying moon, a fatal meaning error.

2. Scientists have found new evidence of people initially registering emotions like sadness or anger in much the same way as heartburn—by monitoring what's going on within their bodies.

A. of people initially registering emotions like sadness or anger in much the same way as[color=#ed1c24] -- people are not intended object of preposition of -- faulty comparison people are compared with heartburn. [/color]

C. that people initially register emotions such as sadness or anger in much the same way as they experience --comparison-- People register || people experience -- correct.
D. that a person initially registers emotions such as sadness or anger much the same way as experiencing -- registers || experiencing

Hi @bagdmba: thanks for posting the correct OAs. :-)

@PiyushK: thanks for the analysis. Note that one modifier can jump over another to refer to the preceding noun. E.g. Option E of the first question:

PiyushK
E. of a star as bright as the full moon that exploded into view 340,000 years ago and that emitted -- same as C -- that modifying moon, a fatal meaning error.

One of the errors here is that the modifier "that exploded..." is ambiguous. It can refer to either the star or the full moon. "As bright as the full moon" is a modifier for "the star". If we remove it, this option will read: "of a star that exploded." This would be correct. So I would call this an ambiguity error. This is one of the reasons that I picked this question to illustrate the topic of this post. The imprecise meaning indicated by the phrase "evidence of a star" is a strong reason to eliminate this choice.

Hope this helps!

Regards,
Meghna

Here in the question as per my understanding aren't we discussing about evidence of "star" though I understand there are other errors in the sentence that makes correct option B ...."????

Lets juxtapose option B with following sentence.

I) Police have found evidence of my brother stealing diamond.
or
II) Police have found that my brother stole diamond.
Option (I) is incorrect because police not found evidence of my brother rather found evidence of his act of stealing.
In option (II) meaning error is corrected in this manner.

Similarly, evidence of a star is not actually what author wants to say; author wants to describe explosion.

As per my observation we use evidence of for action nouns not for proper noun.
e.g evidence of explosion, evidence of stealing ... but I never seen something like evidence of sun or star or car.. any proper noun in this way.
Context and style is important.

Is there any specification for the idiom "Evidence for ". Searched online but the versions are different such as this https://forum.wordreference.com/threads/ ... f.1682498/

Can experts chetan2u specify the usage on GMAT.

Why is the use of 'like' invalid ?
As per my understanding, "sadness or anger" is a noun. So shouldn't we use 'like' for comparison ?
Please explain.

The GMAT doesn't seem to like using like to introduce examples. As sadness and anger are examples of emotions, we'd normally expect the GMAT to prefer such as to like. Also, keep in mind that there is a pronoun mismatch in E (a person followed by their).

Hello ligamenttears,

Thank you for the query. :-)


The phrase "evidence for" is also a correct phrase. This phrase can sometimes be used interchangeably with "evidence of". The context of the sentence will tell us when it can be done and when it cannot be done.


Hope this helps. :-)
Thanks.
Shraddha
