The answer is not 27. It's 81. But you have not transcribed the answer choices correctly. They actually look like this: [81] [54] [36] [27] [18] Of these choices, only [27] is equal to 81.

From statement 1 we know that a = 2b. If a = b = 0, the answer to the question is yes. In all other cases the answer to the question is no. Insufficient. From statement 2 we know that a = b(log3/log2). If a = b = 0, the answer to the question is yes. In all other cases the answer to the question is no. Insufficient. The only values of a and b that satisfy both statements are a = b = 0, and so from the two statements together we can say the answer to the question is yes. The correct response is C. If the question had specified that a and b are integers, statement 2 alone would have be sufficient.

"However much voters may agree..." is perfectly idiomatic and makes perfect sense here. It means "to whatever extent voters agree" or "no matter how much voters agree". Imagine asking this question: "How much do voters agree? Do they agree a lot or a little?" The sentence starts from the position that it doesn't matter how much voters agree: "However much voters agree... it is difficult to find support..."

But would you say: "More work gets done when awake than when asleep"?

E may be parallel, but it makes no sense. It says that the hormone is secreted in higher concentrations when asleep than when awake, meaning that sometimes the hormone is asleep and sometimes it is awake. D not only is parallel -- during + noun (sleep) compared with during + noun (waking hours) -- but also makes sense.

Until about 50 years ago, media and data were used only as countable plural nouns. Traditionalists still treat them exclusively as plurals, and GMAT writers are rather old-fashioned. Nevertheless, because even GMAT writers recognize that today many educated people use media as an uncountable singular noun when referring to the agencies of mass communication, you cannot eliminate an answer choice just because it says "the media has..." In this example, however, there is no doubt that media is plural because of the pronoun they.

In forming the possessive, sometimes you have the option of adding 's or just the apostrophe (without s). Here are the rules: For most singular nouns, add 's: the boy's house, the company's CEO, the state's population For singular nouns that end with -s, you may add either 's or just the apostrophe. Both are acceptable: James's house or James' house, the business's CEO or the business' CEO, Texas's population or Texas' population. For plural nouns that end in -s, add just the apostrophe: the two boys' houses, the two businesses' CEOs, the two states' populations For plural nouns that do not end in -s, add 's: the two children's houses, the two alumni's wives I have a system that makes the issue very easy. Forget about singular and plural. Just follow these two simple rules and you will never make a mistake: 1. If the noun ends with -s, add just the apostrophe. 2. In all other cases, add 's.

You are very kind. I'm sorry I cannot contribute more frequently, but my GMAT and SAT students here in Milan are my first priority.
