1.In Eastland, from 2000 to 2005, the total consumption of fish increased by 4.5 percent, and the total consumption of poultry products increased by 9.0 percent. During this time, the population of Eastland increased by 6 percent, in part due to new arrivals from surrounding areas. Which of the following can one infer based on the statements above?

A For new arrivals to Eastland between 2000 and 2005, fish was less likely to be a major part of families’ diet than was poultry.

B In 2005, the residents of Eastland consumed twice as much poultry as fish.

C The per capita consumption of poultry in Eastland was higher in 2005 than it was in 2000.

D Between 2000 and 2005, both fish and poultry products were a regular part of the diet of a significant proportion of Eastland residents.

E Between 2000 and 2005, the profits of wholesale distributors of poultry products increased at a greater rate than did the profits of wholesale distributors of fish.

2. Everyone who has graduated from TopNotch High School has an intelligence quotient (IQ) of over 120. Most students with an IQ of over 120 and all students with an IQ of over 150 who apply to one or more Ivy League universities are accepted to at least one of them. The statements above, if true, best support which of the following conclusions?

A Every graduate of TopNotch High School with an IQ of 150 has been accepted to at least one Ivy-League school.

B If a person is a high-school graduate and has an IQ of less than 100, he or she could not have been a student at TopNotch High School.

C If a person has an IQ of 130 and is attending an Ivy-League school, it is possible for him or her to have graduated from TopNotch High School.

D At least one graduate from TopNotch high school who has applied to at least one Ivy-League university has been accepted to one of them.

E If a high-school graduate has an IQ of 150 and is not attending an Ivy-League school, then he or she did not apply to one of them.

C

D (X C!)

Remark:

From Ron:

well, the problem is that the passage doesn't give any indication of how many TNHS graduates actually apply to ivy league schools. in fact, even if none of TNHS's graduates applied to ivy league schools, that is still perfectly consistent with the information presented in the passage.

so, let's say that only 1 graduate of TNHS applied to an ivy league school. while it's more likely than not that this student would be accepted, there's a decent chance that (s)he wouldn't be - and that's enough to shoot down choice (d), because it contradicts the definitive language of (d). in other words, we can't be 100% sure that at least one applicant has been accepted.
were choice (d) to make a slightly weaker statement, such as 'it is very likely that...', that would be another story - but, unfortunately, it doesn't say that.

choice (c), on the other hand, makes a very weak, anodyne statement (it is possible...), so it's very easily supported by the content of the passage.
