When the student-teacher ratio of a class exceeds 20 students to each teacher, the students experience greater difficulties in learning. In light of the new hiring freeze for public school teachers, parents should consider sending their children to private schools this year in order to capitalize on the better learning environment.

Which of the following, if true, provides the most support for the argument above?

A) The new hiring freeze on public school teachers will stay in effect for the next two years.
B) Public schools educate a greater percentage of this country's children than do private schools.
C) Private schools have an average student-teacher ratio of 14 students to each teacher.
D) Three years ago, a high student-teacher ratio in the public schools created learning problems for many of the affected students.
E) The increase in federal and state funding for the city's educational system has been cut in each of the last three yearly budgets.

A) The new hiring freeze on public school teachers will stay in effect for the next two years.
B) Public schools educate a greater percentage of this country's children than do private schools.
C) Private schools have an average student-teacher ratio of 14 students to each teacher.

1. B is out. Ok, it is true. But it gives us nothing. Why should parents send their children to private school? Maybe both options are good, maybe both are bad.
2. D is out. This option just gives us an evidence that three years ago were some problems because of a high ratio. But we have all arleady read it in a passge. It is given to us as a fact : "When the student-teacher ratio of a class exceeds 20 students to each teacher, the students experience greater difficulties in learning."
So, nothing new.
3. E is out. Sure, it is a support. But it is to wide. We have to speculate and it is not good. Maybe inspite of these cuts the ratios in public schools are still pretty good (<20 students for 1 teacher) so why have parents to send their children to private schools.

4. Now the small dillemma. Between A and C.

C is good. Nice ratio. But it does not answer the question why parents have to send their children to private schools this year.

I do not like the A option here. Because it does not give us a clue, will the ratio will the more than 20, or not.
Ok, there is a hiring freeze for 2 years. But students come ang go (graduate). Maybe we will not exceed the 20/1 ratio anyway.

But this option is the only one that gives us some link.
Maybe there will be a lot of students in these 2 years, and the ratio will become more than 20/1.
Maybe the teachers will retire, and we can not hire new ones. So the ratio will exceed 20/1.

So, we have to choose the least of the bad, A.

Upd. Irony, I have chosen option C at first. But overthought to much and changed my opinion. A is really overthinking. Sometimes the simplest answer is the best. But the question is bad.
This momen us not clear.
"C is good. Nice ratio. But it does not answer the question why parents have to send their children to private schools this year."
Why this year, why now?

We need to strengthen the argument that parents should send their children to private schools rather than public schools for a better learning environment. Reason for this -
1) Student - Teacher Ratio exceeds 20 students to each teacher.
2) Hiring freeze for public school teachers

(A) The new hiring freeze on public school teachers will stay in effect for the next two years.

Explanation - May be it will have an impact on the ratio (say teachers retire), maybe it will not (count of students will remain same that is why authorities want freeze).
We can not say for sure. Too many maybe's that cannot be answered. We can consider this option if we do not find another more strengthening than this.

(B) Public schools educate a greater percentage of this country's children than do private schools.

Explanation - This point is irrelevant as in the stem we are talking about ratio's, but here we are considering percentages.

(C) Private schools have an average student-teacher ratio of 14 students to each teacher.

Explanation - It seems to be correct. Because if students here increase, private schools have a chance of increasing teachers also keeping the ratio same.

(D) Three years ago, a high student-teacher ratio in the public schools created learning problems for many of the affected students.

Explanation - It seems to be irrelevant as we are not considering what happened three years ago but what will happen this year

(E) The increase in federal and state funding for the city's educational system has been cut in each of the last three yearly budgets

Explanation - It seems to be irrelevant as we are not considering what has happened in the last three cycles but what will happen this year

So IMO (C)
