Q:

Which one of the following air pollutants combines with the haemoglobin of human blood and reduces its oxygen-carrying capacity, leading to suffocation and may cause even death?

A) Chlorofluorocarbon	B) Fly ash
C) Carbon monoxide	D) Sulphur dioxide

Answer & Explanation Answer: C) Carbon monoxide

Explanation:

Carbon monoxide (CO) is very dangerous because it binds with the haemoglobin more efficiently than oxygen does. It "hogs the seats" so that oxygen can't get a ride. And those CO molecules keep riding around, never giving their seats up to the oxygen. This means there is no way to get oxygen to the brain, heart, or other cells and those cells start to die. And finally, it leads to suffocation and even death of a person.

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.

The shortest boy of the school/ didn't hesitate to join/ the basketball team which/ was full of tall boys.

A) The shortest boy of the school	B) didn't hesitate to join
C) the basketball team which	D) was full of tall boys

Answer & Explanation Answer: A) The shortest boy of the school

Explanation:

The error lies in the first part of the sentence. After superlative adjectives, majorly two prepositions are used: of and in. We use in with a singular word referring to a place or group. Eg: I am the happiest woman in the world. We use of before plurals, before time periods such as year/month. Eg: Sunday is the best day of the week. Here, in this case, the subject is the 'school', thus, it should be 'in the school'.
