My proposed choice: (E) less of certain pollutants than do those burning gasoline or diesel fuel Thanks in advance for your help Both of the following are viable: Vehicles powered by natural gas emit less of certain pollutants than those burning gasoline or diesel fuel. Vehicles powered by ndatural gas emit less of certain pollutants than do those burning gasoline or diesel fuel. The inclusion of do is optional. With or without do, the intended comparison is clear: Vehicles powered by natural gas emit less of certain pollutants than those burning gasoline or diesel fuel [emit certain pollutants]. No verb is required in the second clause as long as the intended comparison is crystal clear. Correct: John ate more pizza than Mary. Here, only interpretation is possible: John ate more pizza than Mary ate. Since the intended comparison is crystal clear, a verb is not required in the second clause. Not viable: Russia exports more oil to Europe than the United States. Here, the intended comparison is NOT crystal clear. Two possible meanings: Case 1: Russia exports more oil to Europe than IT EXPORTS OIL TO THE UNITED STATES. Case 2: Russia exports more oil to Europe than THE UNITED STATES EXPORTS OIL TO EUROPE. If Case 2 is intended, a verb is required in the second clause to make the intended comparison crystal clear. Correct: China exports more oil to Europe than DOES the United States. _________________ Mitch Hunt Private Tutor for the GMAT and GRE GMATGuruNY@gmail.com If you find one of my posts helpful, please take a moment to click on the "UPVOTE" icon.

Let us say pollutants emitted are A, B and C. less of certain pollutants: A, B and C are emitted, but the "quantity" of A, B and C would be less. fewer pollutants: Not all the three (A, B and C) will be emitted. Perhaps only A and B will be emitted. Since the original sentence says "less of certain pollutants", changing it to "fewer" would change the meaning. This is my understanding. Let's see what experts have to say. Is it an official question? If yes, can you also post the official explanation?

To quote the staff: * fewer of those pollutants and less of those pollutants have different meanings. the former means that, if you made lists of the pollutants from each of the two sources, then one of the lists would be missing pollutants that were on the other list. the latter means that both lists would contain the same pollutants, but that the quantities would be lower on one side. ### GMAT/MBA Expert GMAT Instructor Joined 25 May 2010 Posted: 15348 messages Followed by: 1864 members Upvotes: 13060 GMAT Score: 790 FEWER of the pollutants = A SMALLER NUMBER of the different types of pollutants. For example: Of the 1000 types of pollutants, only 10 types are emitted. LESS of the pollutants = A SMALLER AMOUNT of each type of pollutant. For example: Of each type of pollutant, only 10cmÂ³ is emitted. _________________ Mitch Hunt Private Tutor for the GMAT and GRE GMATGuruNY@gmail.com If you find one of my posts helpful, please take a moment to click on the "UPVOTE" icon.
