Critics of President Bush's education initiative that required annual testing of students felt that
O it raised standards to levels that were difficult to meet.
O some students would benefit more than others.
students' performances in the sciences would decline over time.
O teachers would focus too much on tests and neglect other subjects.

The right choice is:

Teachers would focus too much on tests and neglect other subjects.

Explanation:

That was the main complaint of the Bush initiative´s critics. Some people pointed at the fact that the new regulations did not address deep educational inequalities in states and nationwide; other critics said that focus on testing was forcing schools to divert resources and staff from other successful programs.

D. teachers would focus too much on tests and neglect other subjects.

Good luck
