which is more than the population of any Western European country.A) which is more than the population of any Western European country.
B) which are more than the population of any Western European country.
C) being more than the population of any Western European country.
D) more than any Western European country in population.
E) more than in any Western European country by population.
Break it down to the basics.
The sentence compares the pet population to the people population. (Yes, the people part is presumed. Bad question, IMHO.)
D - Break it down to the basics, "more than any country". This compares
pet population to country. Wrong.
*Note: If D was rephrased as "more than the population of any country", the comparison would be correct.
E - Break it down to the basics, "more than in any country". This compares
pet population to pet population. Wrong.
C - Just sounds wrong. Who talks like this??
That leaves A & B - a classic is-vs-are dilemma. Remember, it's the pet population we're comparing, not the dogs, cats, states, etc. So, break it down to the basics: "100 million" (or "the pet population") IS more than the people population.
