I've read this a few times already and I still don't get why A is wrong.
I can't even attempt to guess at why it's wrong. What am I missing?
Thanks

Sentence #1: Graphical illustrations make learning geometry easier by giving students a better grasp of geometric concepts which in turn makes it easier to gain the skill of manipulating symbols for calculation.
In summation this sentence is saying "Illustrations makes learning geometry easier by providing students with a skill (intuitive understanding of geometric concepts) that in turn makes it easier to acquire another skill (ability to manipulate symbols) for calculation. This latter skill (ability to manipulate symbols for calculation) can be thought of as a necessary skill for learning geometry. The reason being is that the claim in the first sentence centers around a medium - graphical illustrations - being used to make an already existing process of learning geometry easier. Let me know if you need any further clarification on this point, and I'd be happy to provide it.
(D) This is a bit tricky. In the first sentence the author talks about how graphical illustrations enables students to learn geometry easier by providing a skill (intuitive understanding of geometric concepts) which in turn makes it easier to acquire the ability to manipulate symbols for the purpose of calculation. You can think of it this way: Graphical illustrations are the conduit through which one has an easier time learning a necessary skill of "manipulating skills for the purpose of calculation. It's tricky, and please let me know if I can provide any further clarification on this.
Once again please let me know if anything I wrote needs some additional explanation or just plain sucks. haha
