one way to realize ambiguity of comparison is to think of the elements as subjects of objects of the 2 clauses of comparison. when we read comparison sentences, we ask ourself immediately the sentence is comparing subjects or the object of the 2 clauses, we have high chance of realizing ambiguity. this skill to solve sc problem is the skill to write a sentence. so, gmat makes us able to write.

Hi daagh GMATNinja

In (E) shouldn't there be 'that of' instead of it is for ? The comparison structure ' its weight is far less that it is for' sounds funny but I can't seem to put a finger on what exactly is the problem there.

Will appreciate your input.

Will appreciate your input.

The following example illustrates the problem with (E):

  • "Spud's height is far less than it is for Shaq." - We want the pronoun "it" to refer to "Shaq's height". But so far we have only referenced "Spud's height". So it sounds like we are saying, "Spud's height is far less than Spud's height is for Shaq." That doesn't make any sense.

Now back to choice (E):

Quote:
(E) Officials at the United States Mint believe that the Sacagawea dollar coin will be used as a substitute more for four quarters rather than for the dollar bill because its weight, only 8.1 grams, is far less than it is for four quarters, which weigh 5.67 grams each.

The first pronoun, "its", refers to "the Sacagawea dollar coin" -- no problem there.

We want that second pronoun ("it") to refer to the weight of the four quarters. But so far we have only referenced the weight of the Sacagawea dollar coin. So we seem to have, "... the Sacagawea dollar coin's weight is far less than the Sacagawea dollar coin's weight is for four quarters." That's obviously not the intended meaning. The meaning is much clearer in the correct answer: "... the Sacagawea dollar coin... weighs only 8.1 grams, far less than four quarters..."

I hope that helps!

This question made me dizzy! It took me up to 3 min. To be honest, I had no idea about what the comparison was.
The clue I cling to is the non-underlined part after "far less than" - the "four quarters". Thus the comparison must be between "four quarters" and something else.
(A) and (E) are out because of "rather than".
(B) the comparison is between "dollar coin" and "dollar bill" -> INCORRECT
(C) "four quarters" is compared with "dollar bill" -> CORRECT
(D) similar to (B) - it seems "dollar coin" is compared with "dollar bill" -> INCORRECT

Hence (C)
