560 - Logical Reasoning

Our school district should not spend its money on the new Verbal Advantage reading program. After all, our students get all the reading practice they need by studying history and science.
The argument above depends on which the following assumptions?

1. The Verbal Advantage program would not help the students learn history and science.
2. Other reading programs are just as effective but less expensive than the Verbal Advantage program.
3. The Verbal Advantage program involves only reading practice.
4. Teaching students history and science is more important than teaching them reading skills.
5. The students can already read well enough to study history and science
