Answer 1

Only the intelligent are taught something.

EXPLANATION:

The given sentence in question was written in the negative form while the answer has been changed into affirmative form. An affirmative sentence is the one in which the statement is written in the positive aspect and contradicts a statement or proposition.  

For example: You should drink more water as you look dehydrated. The meaning hasn’t been altered in this sentence and it has been kept the same. The sentence conveys the meaning that things were taught only to the intelligent people and not others.
