Those who have the ability to fully concentrate are always of above-average intelligence. Also, being successfully trained in speed-reading will usually be accompanied by an increased ability to concentrate.

Summary
The stimulus can be diagrammed as follows:

Notable Valid Inferences
Most speed readers have above-average intelligence.

A
Some people can speed-read, and are able to fully concentrate, but are of below-average intelligence.
This must be false. We know that all people who are able to fully concentrate are of above-average intelligence.
B
All people who can speed-read are of above-average intelligence.
This could be true. We know for sure that most speed readers are of above-average intelligence; it could still be true that all are of above average intelligence.
C
Many people of above-average intelligence are unable to fully concentrate.
This could be true. We know that all people who can fully concentrate are of above-average intelligence, but this doesn’t mean that everyone of above-average intelligence can fully concentrate.
D
Some people with little ability to concentrate are of below-average intelligence, but can speed-read.
This could be true. If someone of is below-average intelligence, then they can’t fully concentrate. It could totally be the case that this person has the ability to speed read.
E
All people who can speed-read are able to concentrate to some extent.
This could be true. The only factor related to concentration discussed in the stimulus is “full concentration;” it could be the case that all people who can speed read can concentrate at least a little bit.
