Q:

Read the passage carefully and choose the best answer to each question out of the four alternatives.

My coat's pretty warm, even though it cost £9.99 and came from the flea market. It had a label in it, CHRISTIN BIOR, but I cut it out as soon as I got home. You can't work where I work and have CHRISTIN BIOR in your coat. You could have a genuine vintage Christian Dior label. Or something Japanese. Or maybe no label because you make your clothes yourself out of retro fabrics that you source at Alfies Antiques. But not CHRISTIN BIOR.

As I get near Catford Bridge, I start to feel a knot of tension. I really don't want to be late today. My boss has started throwing all sorts of hissy fits about people "swanning in at all times," so I left an extra twenty minutes early, in case it was a bad day. I can already see: It's a god-awful day. They've been having a lot of problems on our line recently and keep cancelling trains with no warning. Trouble is, in London rush hour, you can't just cancel trains. What are all the people who were planning to get on that train supposed to do? Evaporate?

Which of the following situations creates a 'bad day' for the author?

A) Being caught wearing a cheap brand coat. B) Cancelled trains during London rush hour.
C) When other employees are on time but she is late. D) Having to spend money on expensive clothes.
 
Answer & Explanation Answer: B) Cancelled trains during London rush hour.
