Question 1

Which of the following does Martin Brasier believe in?
Option 3 Uniformitarianism is a powerful tool in some fields but it has certain downsides
It's evident in this part of the passage.
' Uniformitarianism has proved a powerful tool in many fields, Brasier admitted, but it ignores an organism’s profound interdependence with its environment. The theory breaks down in the Precambrian era, when the oceanic ecosystem was radically different'
.

Question2
According to Brasier,principle of uniformity can't be applied to the Precambrian era because it ignores an organism's profound interdependence with its environment.And the oceanic ecosystem was radically different in Precambrian era.

I fail gmat many times and get some experience.

when you read a sentence in a text, you have to realize the grammatical role of
- each phrase, entity
- each tense/verb. for example, if you see simple present, you need to identify this tense is about a habit, or a condition or a timeless fact or a indefinite situation. these are 4 most popular cases of uses of simple tense. all of these cases is explained in grammar book. read this point in grammar book for a few minute and practice see this point in the text you read. This is call " see grammar points in the text" . learning grammar this way is efficient.

-each preposition in the idiom. English has many idiom, most of which are used in idiom with verb and noun. for example, if you see "presentation on" , you should know "on" go with "presentation" to make an idiom.

in short, when you read, you activate your grammar points

Passage


President Donald Trump's combative approach to world affairs is scrambling political dynamics in countries across the globe, bolstering some candidates who promise to stand up to the new U.S. leader and potentially reshaping America's alliances.
1. potentially reshaping
2. who potentially reshape

Questions


Here are the questions for this passage:

1. What is the meaning per choice 1?
2. What is the meaning per choice 2?
3. Are the two meanings the same?
4. Is sentence per choice 1 logically sound?
5. Is sentence per choice 2 logically sound?
6. Is sentence per choice 1 grammatically correct?
7. Is sentence per choice 2 grammatically correct?

I look forward to your responses. Needless to say - kudos for correct and precise responses!

Regards,

Payal

Interesting question :) Let's begin by analyzing the two choices:

Choice-1: "President Donald Trump's combative approach to world affairs is scrambling political dynamics in countries across the globe, bolstering some candidates who promise to stand up to the new U.S. leader and potentially reshaping America's alliances."

Analysis: Ok, so, President Donald Trump's combative approach to world affairs is scrambling the political dynamics in countries across the globe. Fair enough. The next part of the sentence is a comma + -ing structure. This means it must modify the preceding phrase or it must present the effects. Here, it is presenting the effects, which are:
1. bolstering some candidates who promise to stand up to the new U.S. leader
2. potentially reshaping America's alliances
Thus, 'potentially reshaping' is basically denoting one of the effects of President Donald Trump's combative approach and showing how approach is scrambling the political dynamics in countries across the globe. It is noteworthy to notice that the use of 'and' here makes 'bolstering' and 'reshaping' parallel.

Choice-2: "President Donald Trump's combative approach to world affairs is scrambling political dynamics in countries across the globe, bolstering some candidates who promise to stand up to the new U.S. leader and who potentially reshape America's alliances."

Analysis: Hmmmm. Interesting. This choice feels different from the first one. :idea: the word 'who' in the phrase 'who potentially reshape' plays an important role here. Similar to first choice, the comma + -ing structure is presenting the effects, which is bolstering something. So, what is getting bolstered?
1. some candidates who promise to stand up to the new U.S. leader, and
2. the ones who potentially reshape America's alliances.
Thus, 'who potentially reshape' is referring to those candidates who can reshape America's alliances. It is noteworthy to notice that the use of 'and' here makes 'who promise to stand up to the new U.S. leader' and 'who potentially reshape' parallel.

Now, with this understanding let's tackle the questions:

1. What is the meaning per choice 1?
Ans: Clearly, from our analysis it means that President Donald Trump's combative approach to world affairs is scrambling the political dynamics in countries across the globe, and this in turn is bolstering some candidates (who promise to stand up to the new U.S. leader) and is (potentially) reshaping America's alliances.

2. What is the meaning per choice 2?
Ans: Again, President Donald Trump's combative approach to world affairs is scrambling the political dynamics in countries across the globe, and this in turn is bolstering individuals who promise to stand up to the new U.S. leader and who who potentially reshape America's alliances.

3. Are the two meanings the same?
Ans: A big NO!

4. Is sentence per choice 1 logically sound?
Ans: Yes. The President's approach may have these effects.

5. Is sentence per choice 2 logically sound?
Ans: No. Can a few individuals, bolstered by the President's approach change America's alliances? Wow, I'd like to be a person who can change a country's alliances!

6. Is sentence per choice 1 grammatically correct?
Ans: Yes.

7. Is sentence per choice 2 grammatically correct?
Ans: Yes.

Hope I'm correct :)

P.S. Another interesting observation: if we add a comma before 'and' in the original sentence, it would again change the meaning completely. The meaning will then become: President Donald Trump's combative approach to world affairs is having three effects which are:
1. it is scrambling political dynamics in countries across the globe
2. it is bolstering some candidates who promise to stand up to the new U.S. leader, and
3. it is potentially reshaping America's alliances.

Hi,

I believe you have given a thorough explanation to this but i was wondering that why answer to question no. 5 is "No".

Statement-"President Donald Trump's combative approach to world affairs is scrambling political dynamics in countries across the globe, bolstering some candidates who promise to stand up to the new U.S. leader and who potentially reshape America's alliances."

Analysis- 1. Statement(Cause)-President Trump's approach is scrambling politics across the globe .
2. Effect-Supporting candidates who stood up to him and who would potentially reshape America's Alliances.

I don't think this line of reasoning is logically incorrect.

Any explanations please?

Here comes Passage for Feb 6

Quote:
The belief that Aztec in New Mexico was constructed during two distinct construction periods has been proven by the modern tree-ring dating and has also been corroborated nicely by other evidence found in the 1920s by archaeologist Earl H. Morris that Aztec actually was built by one group of people - Chaco tribe whose settlement is indicated by the absence of burials - abandoned, and then reoccupied at a later date by a slightly different group of people - Mesa Verde tribe whose pottery, household utensils, and burials were found overlying the Chaco debris and sterile sand layers.

Here are the questions based on this 99-word sentence. Notice that for this exercise, I will not present options. I want you to tell me the answer in your own words.
According to the passage,
1. What is the belief about Aztec?
Answer: The belief was that Aztec in New Mexico was constructed during two distinct construction periods
2. What are the two ways in which this belief has been proven?
Answer: 1- By the modern tree-ring dating
2- By other evidence found in the 1920s by archaeologist Earl H. Morris

3. What was abandoned?
Answer: Aztec
4. Who abandoned?
Answer: By Chaco tribe
5. What is the point of difference between Chaco tribe and Mesa Verde tribe?
Answer: Chaco tribe : Absence of burials Mesa Verde tribe: Presence of burials

Please find my answers in bold.
