Read the sentence to find out whether there is an error in it or not. The error, if any, will be in one part of the sentence. The number of that part is the answer. If there is no error, the answer is (5). Ignore errors of punctuation, if any.
My brother has a (A)/ fear of trains and (B)/ therefore, he (C)/ always travels in plane. (D)/
The error is in D). You travel by plane or by train, not in it. It is important that we remember that 'by' is used with travel except in certain situations.
When we are talking about general ways to travel, we always use the preposition “by.”
When we are talking about certain transport vehicles in which we can sit inside the vehicle, we use in.
Some examples would be: "in a car", "in a truck".
If we can stand or walk on the vehicle, then on can be used. Examples: We go on a ship.
We can also say: 1. Take something to read on the plane.
2. Everyone got in the plane and found their seats. However, with 'travel' we always use 'by'.
Correct sentence - My brother has a fear of trains and therefore, he always travels by plane.
