In the question given below, the sentence is divided into three parts I, II and III. For each part an alternate statement is also given. You have to determine if a part requires correction, and then mark that as your answer.
Limiting the supply of a certain imported product, while / increasing prices paid by consumers, allow local producers a chance / to improve their position in the market by filling the unmet demand.
I. Limited the supply of a certain imported product, while
II. increasing prices paid by consumers, allows local producers a chance
III. to improving their position in the market by filling the unmet demand.
The error lies in part 2.
The sentence uses the plural form of the simple present tense verb 'allow'. This is incorrect as we are referring to 'one activity' (limiting supply of products), so we must use the form 'allows'.
Parts 1 and 3 are grammatically correct and hence do not require any corrections.
Therefore, the correct answer is option 5.
2. In a bad way
5. What is the substitute of - A drug or other substance that induces sleep
