Hint: In the given question the blanks are needed to be filled with suitable nouns. In the given question the blanks are needed to be filled with suitable nouns. A noun is a word that refers to a person, a place, an object, or a concept which may be used as the subject, direct object, indirect object, subject complement, object complement, etc.
The given sentence can be divided into the general structure, subject-verb-object. “The ___of the forest” is the subject. “Will result” is the verb and “in” is the preposition. The last part, “the ___ of many animal species” is the prepositional object. The subject and the object in a sentence should always have a noun or a noun phrase. Therefore, the blanks have to be filled with nouns. Now, let us find out which of the given pairs is suitable for filling the blanks.
Now let us look intot he given options:
Option A) Destruction/disappear – ‘Destruction’ is the noun form of the verb ‘destroy’, and hence it is a correct choice for the first blank. The word ‘disappear’ is a verb, but the second blank needs to be filled with a noun. Therefore, this option is wrong.
Option B) Destruction/disappearance – In this option ‘destruction’ is a noun and is correct for the first blank. Also, ‘disappearance’ is the noun form of the verb ‘disappear’ and hence it is also correct for the second blank. Thus, this option is correct.
Option C) Destructing/disappear – The word ‘destructing’ is a present participle verb and is not suitable for the first blank. The word ‘disappear’ as we already know is also a verb and is not suitable for filling the second blank. Hence, this option is incorrect.
Option D) Destruct/disappearing – Here, the word ‘destruct is a verb and it cannot be used for the first blank. The word ‘disappearing’ is a present participle verb or a gerund and is not suitable to fill the blank. Neither of them are nouns and thus, the option is wrong.
Thus, the correct answer is Option (B) i.e, The destruction of the forests will result in the disappearance of many animal species.
Note: Anything that can be seen, handled, eaten, smelled, or smelt is referred to as a concrete noun. A concrete noun, in other words, is something you can feel in at least one of your senses. A concrete noun may be thought of as the polar opposite of an abstract noun. (An abstract noun is something you can't see through your eyes or hear with your ears.)
