Why are there more likely to be more technical terms in a phone repairman's

manual than in a television program guide?

A. Phone repair requires detailed knowledge of how phones work.

B. Knowledge of choosing television programs requires the use of

many technical terms.

C. Televisions are easier to repair than phones.

D. More people use telephones than televisions.

A. Phone repair requires detailed knowledge of how phones work.

Explanation:

Technical terms refer to words related to a particular subject or science. In that matter, a phone repairman's manual constains specific vocabulary concerning the components of a phone, inside and outside, as well as how those parts function in combination to make a phone work.

The rest of the alternatives are incorrect because they do not involve the fact that a phone manual has more technical terms than a television guide.
