Question

Fill in the blank with the most appropriate prepositions:
Many people are of the opinion that the 3rd World War will be fought ___ oil.
a) for
b) from
c) at
d) over

Answer 1

Hint: A preposition is a function word that combines with a noun or pronoun or noun phrase to form a prepositional phrase that can have an adverbial or adjectival relation to some other word.

Complete answer:
In the given question, we know that oil is a non-renewable resource. Thus, due to the shortage of oil, people think that WWIII will be due to oil.
Let us thus analyze the options given to us in this question:
Option (a.), 'for', refers to ‘Directed at, intended to belong to.’
Therefore, option (a.) is incorrect as it does not indicate the importance or concerning the role of oil.
Option (b.), ‘from', refers to ‘With the source or provenance of or at.’Therefore, option (b.) is incorrect as it indicates that oil will be used to fight, which is not the needed implication.
Option (c.), ‘at', refers to ‘In or very near a particular place.’Therefore, option (c.) is incorrect as oil is not a place.
Option (d.), ‘over', refers to ‘concerning or regarding.’Therefore, option (d.) is correct as it describes how oil is a concerning resource over which WWIII can be fought.

Note:
 In this question, it will be helpful for the student to recall the concept of logical reasoning, as these types of questions require it. Logical reasoning includes thinking that is capable of or reflecting the capability for correct and valid reasoning.
