Exercise: 5 / 12

Purpose: Many uncountable nouns can also have a countable form. Such nouns are known as two-way nouns. This exercise offers practice in deciding whether an indefinite or no article is appropriate for the same noun in different contexts.

Instructions: Each question will present two sentences using the same noun: one requiring the uncountable version of the noun and the other using the countable form. For each sentence, you will need to decide which article (a/an) or no article (Ø) is correct for that context.
