[amp_mcq option1=”especially of” option2=”especially in” option3=”in special of” option4=”No improvement” correct=”option1″]
The correct answer is (A).
The preposition “of” is used to indicate a specific subject or area of study. In this case, the writer is saying that there is a shortage of well qualified teachers of English and Economics.
The preposition “in” is used to indicate a location or position. In this case, the writer is not saying that there is a shortage of well qualified teachers who are located in English or Economics departments.
The preposition “special” is an adjective that means “remarkable or unusual.” In this case, the writer is not saying that the shortage of well qualified teachers is remarkable or unusual.
The phrase “in special” is not a grammatically correct phrase.
Therefore, the correct answer is (A).
