Answer 2

We are provided with an incomplete sentence that requires to be completed by using an appropriate word. No word that will be used to fill the gap in the sentence because the sentence is already complete.

• Three articles are there in English , namely,  a, an, and the. Articles are to be used before nouns or equivalents of noun and are a kind of adjective.
• "The" is a definite article and is used before a noun to indicate that the identity of the noun is already known to the reader of the text.  
• "a, an" being the indefinite article are used before a noun that is either general or when its identity is unknown.
• There are also certain special situations in which a noun takes no article. Our question given falls into that category.
• When a plural countable noun is generic or nonspecific then no article is used . No article is used when a noncountable noun is also generic or nonspecific.

• Definite article "the" is used before a singular or plural noun.

• Indefinite articles :

• a (used before a singular noun which begins with a consonant sound)

• an (used before a singular noun which begins with a vowel sound)

Therefore, the sentence using the word very will be written as "The box was made of wood. "
