Although she had been known as an effective legislator first in the Texas Senate and later in the United States House of Representatives, not until Barbara Jordan’s participation in the hearings on the impeachment of President Richard Nixon in 1974 was she made a nationally recognized figure, as ...

From Papgust's Flash Card: "Which" is used as a relative pronoun ONLY to refer to the NOUN immediately preceding it. In other words, "Which", by default, refers to the noun that is closest to the left of the comma. WHAT TO DO if "Which" seems to refer to the action of t...

E is not parallel: to think, to assess, doing.
In B, semicolon before 'because' doesn't seem right.
Only A is parallel: thinking, assessing, doing.
Eventhough it is wordy, [spoiler]A makes sense and doesn't have serious grammatical errors and so I shall go with A[/spoiler]

If we re-write the first statement (x2-5x = -6) as
(x2-4)/(x-2) = 5, it will have the same issue as statement 2.
So isn't it true that we have to consider both roots of statement 2 as valid?

Interesting question on algebra
What is the value of x2-1?
(1) x2-5x = -6
(2) (x2-1)/(x+1) = 1
(x2 is x squared)
OA is B, but I think it should be C. One question to the experts, is 0/0 = 1? Thanks.

Read it this way -- forget the yellow part for the moment and read the sentence. By the year 2000, A Tale of Two Cities, Charles Dickens' gripping book portraying the suffering of the proletariat under the brutal subjugation of the French aristocracy , had around 200 million copies in print, more t...

Hey Gokhra, I had gotten E too but checked it a different way with rewriting it as: is f^2> f^2-f ? Unless my logic is incorrect, I cannot decide between choice B and E Your logic is incorrect. This is not a valid way to rewrite the inequality. I assume you got this by multiplying both sides of the...

When in doubt, try replacing 'who/whom' with 'he/him', to check whether it makes sense.sam2304 wrote:IMO E.
Use Who when the noun is a subject. Use whom when the noun is an object.
In this sentence, we don't 'call he something', but 'call him something'

Thanks Brent & GmatMathPro! I came across the below problem from Kaplan, which confused me. I could only solve it using probability and then I got the wrong answer! For each 6-month period during a light bulb's life span, the odds of it not burning out from over-use are half what they were in th...

In Gmat questions, is there a differentiation between the terms 'odds' and 'probability' or are they both used to refer to probability? I have seen probability questions where the term 'odds' is used. At the same time, Kaplan uses them to refer to only 'odds' For example, in the above question, odds...
