Option A
Statement 1 is enough. We have that r = 6u, and we have that all r, s, t, u are non-zero digits, i.e. in the range from 1 to 9 (both inclusive). There is only one such combination: u = 1 (because if u = 2, r becomes 12, which is not possible). And since we know the unique value of u, we know that x ...

I'm stuck as well !!
D does not use the comparative form "faster" as well as E. But, if I remove the sentence between the two commas, it should still hold. And that happens with option D. I think I'm going with option D. Last year, land values in most parts of the pinelands rose almost as fast as (, and in som...

I think D
Examples of neurogenesis can't be mice and canaries; it can be brain growth in mice and increase of neurons in canaries. That does away with B and C. A does not use the right noun form "growth". Now left with D and E. E uses " ... brain growth ... an increase ... ". I would prefe...

Option B
"natural outgrowth" is not associated with "coolness of judgment and mutability of purpose". It is associated with "religious zeal". It has to stay singular. Option B is right.

missing pronoun / noun
Its not the archaeologists who are destroyed. So I am only looking to remove the ambiguity by either providing what is destroyed, or clarifying the noun / pronoun that the modifier applies to.
Option C.

I'll choose A
I don't like the use of "done" in C, D, E. The act of speaking French in the family is not a one time action. Hence I prefer the use of "been", as it reflects continuity in action. Option B does not use the verb properly; and so I'll stick to A. Although I agree with the earlier ...

OA is C
Statement 1: 2x - 2y = 1 Lets take an example: 4 - 3 = 1 OR (-4) - (-5) = 1. Thus we can't say for sure if X and Y are positive. Also: 1 - 0 = 1 and 0 - (-1) = 1. So, both need not be positive or negative simultaneously. Statement 2: (x/y) > 1 This means that either both X and Y are positive (in whi...

pronoun reference to Quetzalcoatlus
The sentence is .... Quetzalcoatlus had a wingspan of 36 feet, believed to be the largest flying creature the world has ever seen. Option A is okay if the latter part of the sentence was qualifying the object "wingspan of 36 feet". But the sentence says "largest flying creature",...

Properties of slopes
Except for Slope = 0 (x axis or parallel) OR undefined (y axis or parallel), we can say that a positive slope always passes through quadrants I & III, a negative slope will always pass through quadrants II and IV. Passing through the other quadrants is not guaranteed. The second statement is ins...

the verb "rose"
Since the first part of the sentence uses the verb "rose", I would use the verb "did" in the underlined part. If the sentence was: The empl. costs were 15% in the year ending in the current quarter, 35% more than what they WERE in the year ending in the previous quarter. However,...

Answer E
In half hour, Carlos could have traveled greater than 6 miles only if his speed was greater than 12 mph. 1 mile = 5280 ft. Thus 12 miles = 63360 ft = 17.6 ft / sec. Stmt 1) Avg speed is greater than 16 : NOT SUFFICIENT Stmt 2) Avg speed is less than 18 : NOT SUFFICIENT Stmt 1 & 2) Avg speed is 1...
