Lesson: Answering Certain Question Types

Comment on Answering Certain Question Types

My answer for the first paragraph (meteor streams) was D. I thought this was correct because we are discussing two natural phenomena right? First, a meteor stream is described, then a meteor shower is explained, and t is also described how these two are related: that a meteor shower occurs when earth passes through a meteor stream. Where am I going wrong here? (thanks for your help)

Aside: This is an official GMAT question.

In their solution, the test-makers state "only a single phenomenon is described in the passage," but I think you have raised a valid point. It seems that the passage describes both a meteor stream and meteor shower is explained.

However, I wouldn't say that the passage demonstrates a way to measure BOTH of them (as answer choice D states)

would you plz summarize the first passage (meteor stream)
thanks

How about: Model confirms broadening theory but not dense center theory.

Or I might even write: Model confirms 1 theory but not other.

7. Which of the following, if true, would most weaken the author’s assertion that, in the 1970’s, corporate response to federal requirements (lines 18-19) was substantial
(A) Corporate contracts with minority-owned businesses totaled $2 billion in 1979.
(B) Between 1970 and 1972, corporate contracts with minority-owned businesses declined by 25 percent.
(C) The figures collected in 1977 underrepresented the extent of corporate contracts with minority-owned businesses.
(D) The estimate of corporate spending with minority-owned businesses in 1980 is approximately $10 million too high.
(E) The $1.1 billion represented the same percentage of total corporate spending in 1977 as did $77 million in 1972.

Here's the portion that deals with the above question:
"Corporate response appears to have been substantial. According to figures collected in 1977, the total of corporate contracts with minority businesses rose from $77 million in 1972 to $1.1 billion in 1977."

So, contracts rose from 1972 to 1977.
Answer choice B talks about what happened BEFORE 1972, so it has no bearing on the rise from 1972 to 1977.

Answer choice E, however, suggests that the increase from 1972 to 1977 was not an increase at all, if you look at the PROPORTION of all corporate spending.
So, for example, if in 1972, $77 million represented 10% of all corporate spending, and in 1977, $1.1 billion represented 10% of all corporate spending, then one might argue that corporate response to federal requirements was NOT substantial.

Does that help?

Hi Brent,

Please refer the passage : https://gmatclub.com/forum/when-the-object-designated-1992-qb1-was-discovered-news-reports-231027.html

Could you please explain why is answer choice B incorrect for Q No. 2(The passage author implies which of the following about news reports concerning 1992 QB1?)? I know why D is correct but unable to figure out the logic behind eliminating B.

Thanks & Regards,
Abhirup

Here's question #2:

The passage author implies which of the following about news reports concerning 1992 QB1?

(A) They exaggerated astronomers' excitement about the object.
(B) They contained inaccurate information about the size of the object.
(C) They initially reported that the object was in the Kuiper Belt.
(D) They incorrectly identified the object as a planet.
(E) They prematurely identified the object as an ice dwarf.

The passage says "When the object designated 1992 QB1 was discovered, news reports suggested that there were now ten known planets in our Solar System. In fact, the object is too small to qualify as a planet"

This doesn't suggest that the reports were wrong about 1992 QB1's SIZE. Instead, the reports were wrong to suggest that 1992 QB1 was a planet.

Here's an analogous passage.
When I first saw my friend's dog, I told everyone that my friend owned a Saint Bernard. In fact, the dog is too small to be a Saint Bernard.

The passage doesn't suggest that I was wrong about the SIZE of the dog; the passage suggests I was wrong to classify the dog as a Saint Bernard.

Does that help?

Cheers,
Brent

Yes Brent I got it now!! As always your explanations make life so easy.

The passage says "Researchers also measured land-tenure security: in Tawahka society, kinship ties are a more important indicator of this [land-tenure security] than are legal property rights."

In other words, when it comes to land-tenure security, kinship ties are greater than legal property rights.

Answer choice A - part i: The security of a household's land tenure depends on the strength of that household's kinship ties. This is a great match with the passage.
--------------------------------------

The passage goes on to say ". . . so researchers measured it [land-tenure security] by a household’s duration of residence in its village."

Answer choice A - part ii: The duration of a household's residence in its village is an indication of the strength of that household's kinship ties. This aligns perfectly with the passage.

Answer: A

Question 2: In using the word “understandable” (line 14), the author most clearly conveys

That part of the passage reads "In the Pullman contest Randolph faced formidable obstacles. The first was Black workers' UNDERSTANDABLE skepticism toward unions, which had historically barred Black workers from membership."

KEY INFORMATION: We're told it took Randolph TEN YEARS to get his union recognized. Then we're told that, the union was finally recognized in 1935. So, Randolph would have begun his quest in the 1920's.

Now let's examine the answer choices...

(A) sympathy with attempts by the Brotherhood between 1925 and 1935 to establish an independent union
There's a timing problem with this answer choice.
At line 14 in the passage, we're examining Randolph's EARLY years leading the Brotherhood. So, when we get to "Black workers' UNDERSTANDABLE skepticism," we have no idea that Randolph will be experiencing difficulties from 1925 to 1935.
ELIMINATE A

(B) concern that the obstacles faced by Randolph between 1925 and 1935 were indeed formidable
Same timing problem as in answer choice A.
ELIMINATE B

(C) ambivalence about the significance of unions to most Black workers in the 1920’s
There's nothing to suggest Black workers were ambivalent about the significance of unions.
ELIMINATE C

(D) appreciation of the attitude of many Black workers in the 1920’s toward unions
The time frame works!
The Black workers were skeptical, and this was understandable (Since Black workers were historically barred from union membership).
KEEP D

(E) regret at the historical attitude of unions toward Black workers
The passage reads "The first was Black workers' UNDERSTANDABLE skepticism toward unions..."
There's no mention or suggestion of regret here.
ELIMINATEE

Answer: D

Brent
