305 Bot #25 answer andexplanation

25. (D). The letter writer...[entire explanation,which refers to a differentquestion]

25. (B). This question is an Analyze

the Argument Structure question; the

best approach is to identify the

conclusion, and then check each

boldface portion of the question for

how it relates to the conclusion, and

eliminate incorrect answer choices on

that basis. Here, the second boldface

is the conclusion of the argument, as

highlighted by the use of the signal

word “Therefore.”

(A) The first boldface is not an

assumption, as assumptions are, by

definition, unstated. Also, the second

boldface does not just describe the

argument’s recommended position, it

is itself the conclusion of the

argument.

(B) CORRECT. The first boldface is a

consideration that helps explain why



companies charge as much as

possible for new designs. The second

boldface presents a different strategy

endorsed by the argument, of

charging less than the greatest

possible price to maximize profit.

(C) The first boldface is not an

assumption, as assumptions are, by

definition, unstated. The second

boldface is not the strategy referenced

in the first boldface, as this answer

choice suggests.

(D) The first boldface does not

demonstrate that the strategy of

selling for the greatest price will not

apply, but instead supports it. Also,

the second boldface is the argument’s

conclusion itself, not a factor in

support of it.

(E) The description of the first

boldface is accurate; however, the

second boldface is not a factor against

the strategy of maximizing profits by

charging the greatest possible price,

but an alternative strategy altogether.

38. (C). 38. (D).

{Editor's note: The detailedexplanation for why the answer is D istoo complex for the GRE, and thisquestion will be removed in a futureedition. Any x = [k - 1 + squareroot(k

2+

2k + 5)]/2, where k is a positiveinteger, will work for the constraints. All such x values EXCEPT the onerelied on in the current explanation aregreater than Quantity B.}

536 Mid #17 answer 17. III, IV, and IV only. 17. III, IV, and V only.

548 Mid #11 {Fraction bar lengths are notdistinct enough.}

{Make the fraction bar between (1/1)and (1/5

-2) longer. That is, the middle

of the three bars should be thelongest.}

557 Mid #11 answer 11. (E). 11. (A).

557 Mid ...the lowermost portion of the fraction, 1/5

-2, is simply

equal to 52.

...the lowermost portion of the fraction,1/5

-2, is equal to 5

2. The uppermost

portion of the fraction, 1/1, is justequal to 1.

557 Mid {Fraction bars do not matchthose in the question itself.}

{cut the first fraction}

557 Bot Dividing by 1/5-2

is the

same...{erroneousfraction}...the answer issimply 5

2, or 25.

Putting these together, the original

fraction can be simplified. {Fractionfrom the question} = 1/52

= 1/25,which is the final answer.

586 Mid #38, end of explanation

Since x + y = 11, y = 9 andQuantity B is greater.

Since x + y = 11, y = 7 and Quantity Bis greater.

1025 Top #13 answer 13. 225,000. 13. 250,000.


47. 36.6. To calculate firstfind the squared differencesbetween the average andthe terms. For example, thedifference between theaverage, 4, and the firstterm, -1, is 5. 5

2= 25. Do

this for all four terms.

47. 36.4. To calculate, first find thesquared differences between theaverage and each of the terms. For example, there is a difference of 4between the average, which is 3, andthe first term, which is -1. The squareof this difference is 4

2= 16. Repeat

for the other three terms.


−1: (4 − (−1)) = 5 = 25 -1: (3 − (-1)) = 4 = 16


4: (4 − (0))2

= 42

= 16 4: (3 − (4))2

= (-1)2

= 1


30: (4 − (30))2 = (−26)

2=

67630: (3 − (30))

2= (-27)

2= 729


−21: (4 − (−21))2

= (25)2

=625

-21: (3 − (-21))2

= (24)2

= 576


Add all of these termstogether: 25 + 16 + 676 +625 = 1,342.

Add all of these terms together: 16 +1+ 729 + 576 = 1,322.

1045 Top #47explanation

Square root of 1342 =36.633.

Square root of 1322 ≈ 36.359.
