Question

Fill the blank with a suitable article:

When was _____ paper first made? (General sense)

• A. a
• B. an
• C. the
• D. no article

Answer 1

Answer: (D)

no article

Paper is an uncountable noun unless a numeral adjective is used. Here, paper, in general, is being mentioned, hence no article is required. Option D is correct here. Indefinite articles are not used for uncountable nouns, hence their usage in the given context is incorrect. 'The' is used for specific nouns, the noun being non-specific here, makes Option C incorrect.
