15. A) A car dealer.

　　B) A mechanic.

　　C) A driving examiner.

　　D) A technical consultant.

　　W：Its always been hard to get this car into first gear. And now the clutch seems to be slipping.

　　M：If you leave the car with me, I will fix it for you this afternoon.

　　Q：Who is the woman probably speaking to?

　　B)。 四個選項都是職業名稱，因此推測本題考查說話人的身份。兩人的對話中提到了this car，first gear，clutch，fix it for you等關鍵詞，而且男士說要為女士修車，可見女士的說話對象應該是機修工。故正確答案為B)。
