Man:You looked worn out! Are you feeling under the weather?
Woman: Not at all. But I have(haven't) been putting in some
wrong errors in the chemistry lab.
Q:What does the woman mean?
Ans:(A) she thinks the wearier is pleasant.
(B) she has been working hard in the lab.
(C) she is not feeling very well today.

這個女生說話很不清楚,我看到的兩個版本一個是have 一個是haven't
不過我都不知道put in some wrong errors in the chemistry lab是什麼意思,麻煩各位大大解答一下了^^
