A、He frequently gets things mixed up. B、He is always finding fault with Marsha. C、He has been trying hard to cover for Marsha. D

W: What is it, Bob? You sounded pretty serious on the phone. Have we still got a budget problem?
M: I don’ know. I hope not. The meeting’s on Friday. But that’s not what I want to talk to you about. Er, close the door, will you? It’s Marsha.
W: Marsha? What about her?
M: I’m worried. I don’t know what to do. She’s just not performing. We may have to let her go.
W: Fire her? She’s been with us a long time, Bob. If she leaves, it’ll be a big loss to us. She’s done really excellent work.
M: Yes. But lately, the last month or so, in fact, there have been a lot of problems. She’s changed. Not only does she have a tendency to be moody all the time, but she misses appointments, doesn’t follow through on projects, and doesn’t seem to plan anything till the last minute.
W: Em, did she ever explain why she didn’t show up for the Denver trip?
M: No. She said she was sorry and that it wouldn’t happen again. Something about a mix-up on arrangements to get to the airport. Now, whenever anybody mentions the subject to her, she just goes silent. I don’t know. Thank goodness. David pulled us out of the hole on that one.
W: Yes, he did a really fine job, filling in for Marsha like that at the last minute.
M: I don’t think it was the first time he’s had to do that. If we knew all the facts, I think we’d find that he’s been covering for Marsha on quite a few projects.
