Question 1
mSKR
Hi
IanStewart GMATNinja CrackVerbalGMAT GMATRockstar BrightOutlookJennQuote:
1. The primary purpose of the passage is to
B. assess the influence that theories of history had on developments in the field of biology in the nineteenth century
C. discuss the importance of historical explanation in the thinking of nineteenth century biologists
We should reject B only because it is mentioned theories of history? Actually I liked B because whatever was derived by 19th century biologists depends on historical explanation .So it means historical explanation had influence in development . But assess means estimate. 1st line of 2nd passage says: partly attracted , so I took it as kind of assess. Somehow i ignored "theories" and end up in choosing B.
I rejected C because biologists were adding experiments beyond what was given in historical explanation. But I am still confused whether I consider this consideration as importance? Infact as experiments add value to the historical explanation so it should be discussion the importance of experiments /methods of 19th century.
Please share your insights once again on primary purpose question:)
Thanks!
To answer primary purpose questions, first break down the structure of the passage as a whole:
In the first paragraph, the author:
- Introduces a turning point in the history of biology: from a "historical explanation" to "experimental manipulation."
- Says that the "historical explanation" era is important to the discussion and gives some further info.
In the second paragraph, the author:
- Explains why biologists liked the historical explanation
- Raises an issue with the historical explanation ("The argument that these scientists employed confuses temporal succession and causal explanation.")
In the third paragraph, the author:
- Raises a difficulty with the historical explanation ("the factual record of the history of life on earth (e.g., that provided by fossils) was incomplete."
- Explains the solution to this difficulty.
Overall, the author's purpose is to discuss the history of biology, and particularly how the historical explanation is important to that discussion. Sure, he/she
mentions experimental manipulation -- but only in passing.
Which answer choice best captures the author's primary purpose?
Quote:
A. compare the information about organic function made available by historical explanation with that made available by the experimental investigation of living organisms
The author does not tell us about the information gleaned from experimental instigation. So, there isn't a clean comparison between the information made available by the two different methods.
(A) is out.
Quote:
B. assess the influence that theories of history had on developments in the field of biology in the nineteenth century
The author discusses the biologists' "historical
explanation" at length -- but that's not quite the same as
"theories of history". "Theories of history" would be some kind of conceptual underpinning used by historians. The author doesn't go into anything like that, so (B) is out.
Quote:
C. discuss the importance of historical explanation in the thinking of nineteenth century biologists
This one looks pretty good. The author states that "it is impossible to discuss the history of biology in the nineteenth century without emphasizing that those areas of biology most in the public eye had depended on historical explanation." Then, he/she spend the rest of the passage discussing the historical explanation.
Keep (C) for now.
Quote:
D. contrast biologists' use of historical explanation during the early nineteenth century with its use during the final quarter of the nineteenth century
Nope, biologists shifted
away from the historical explanation during the final quarter of the nineteenth century -- so it's a bit off to say that the author contrasts how BOTH the earlier and the more recent biologists used the historical explanation.
Eliminate (D).
Quote:
E. evaluate the way in which the concept of heredity altered the use of historical explanation by nineteenth-century biologists
Heredity is mentioned near the end of the passage. However, it is only included as a small detail in a much broader discussion of biologists' historical explanation. So, the bit about heredity isn't the author's primary purpose for writing the passage as a whole.
Eliminate (E). (C) is the correct answer to question 1.
