The following sentence is broken into four parts and two may contain an error in them. Find out the combination which contains the error. If the sentence is free of error, mark 'No error'. If your productivity has stocked, (A) or your frustration level has peaked at a new height, (B) it may be that too many (C) other things is on your mind. (D)?

Option 1 : AD

The correct answer is option 1.

The errors in the sentence are in part A and D.

In part A, the word 'stocked' in incorrectly used as it means to 'amass supplies of something, typically for a particular occasion or purpose' and does not fit the context of the sentence. Thus, the word to be used is 'stalled' which means to 'stop or cause to stop making progress'.

in part D, the word 'is' is incorrectly used as it is the incorrect conjugation of the verb 'to be'. The subject of the second part of this sentence is the 'other things' which is in the plural form, and so 'are' is the correct form of the verb to be used.

Thus, the sentence will result in as follows:

"If your productivity has stalled, or your frustration level has peaked at a new height, it may be that too many other things are on your mind".
