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?

The author would prefer to be seen wearing all of the following types of clothes, except?

A) Those with the Christian Dior label. B) Any Japanese brand.
C) Clothes stitched by herself. D) Those with the CHRISTIN BIOR label.
 
Answer & Explanation Answer: D) Those with the CHRISTIN BIOR label.

Q:

Read each sentence to find out whether there is any error in any part

Sita(a) with all her sisters(b) were here(c). No error.(d)

A) a B) b
C) c D) d
 
Answer & Explanation Answer: C) c

Explanation:

‘Were’ needs to be replaced with ‘was’ to make the sentence grammatically correct. This is because, ‘If the subjects are joined by as well as, with, along with, together with, and not, in addition to, but, besides, except, rather than, accompanied by, like, unlike, no less than, nothing but, led by, headed by, guided by, controlled by, governed by,etc.. Then the verb will agree with the first subject’ Thus, the correct sentence would be, ‘Sita with all her sisters was here’.
