C) cooler than the rest of the Sun's surface.	D) None of the above

Answer & Explanation Answer: C) cooler than the rest of the Sun's surface.

Explanation:

Sunspots are a magnetic phenomenon on the Sun.

The reason a sunspot appears dark is that they are cooler than the rest of the Sun's surface and also the gas inside the spot where the magnetic field is strongest is only emitting about 1/4 as much light as from the rest of the solar surface.

Q:

Read the sentence to find out whether there is any error in it. The error, if any, will be in one part of the sentence. If the given sentence is correct as it is, the answer is ‘No error’. Ignore the errors of punctuation, if any.

Sometimes, when you are used to/ see a player in the commentary/ box over a long period, you tend to/ forget what a great player he was

A) Sometimes, when you are used to	B) See a player in the commentary
C) Box over a long period, you tend to	D) Forget what a great player he was

Answer & Explanation Answer: B) See a player in the commentary

Explanation:

The error lies in the second part of the sentence. The form V + -ing is called a gerund if it serves as a noun. In the given sentence "to" has been used as a preposition (in a prepositional phrase) and not an infinitive, thus, the gerund form "seeing" is correct. E.G. I look forward to meeting my relatives. Thus, option 2 is correct. Here, 'used to' is used in the present tense to indicate that one has a habit of doing something.
