Preposition 1

This category refers to questions that have problems with individual prepositions.

There are two main types of preposition problems.

1. An incorrect preposition is used.

Ex. I thoroughly enjoyed meeting you last week and talking over (A) the project that (B) we will be working in (C)  together next year to (D) ensure mutual benefit. 

2. A preposition is omitted.

Ex. Most (A) the environmental hazards are caused by (B) human activities and lack of (C) awareness towards conservation of (D) the environment. 

In this example, A is incorrect, “most the” should be “most of the”.
