Hi @tomgbean,

We're looking for a proposition that the facts in the stimulus can lead us to infer. So what do those facts tell us? Schools with computer technology teach computer skills at the expense of teaching basic math and reading skills. So we see that one skill is being taught at the expense of others, and this is what (D) tells us. I wouldn't worry too much about the use of the phrase "educational development" here, as it is clear that computer skills and classroom computers are a type of "educational development" mentioned here, and we are looking for general principles that we can infer from these facts.

In any case, (D) is a better answer than (B) because of the strong language used in (B). (B) tells us that schools CANNOT emphasize teaching computer skills without neglecting other basic skills. It's possible that there are other schools that can teach both without neglecting the other, or that future technological developments will allow both kinds of skills to be developed. Hope this helps.
