Fill in the blank with the suitable article: ____ sugar is bad for your health.

Answer: Some

"Some" is correct because it indicates an unspecified amount and is commonly used with uncountable nouns when referring to an indefinite quantity.

Note on uncountable nouns and articles: when speaking about an uncountable substance in general, no article is often used (for example, "Sugar is bad for your health"). However, among the given choices, "Some" is the most appropriate because it conveys an unspecified amount of sugar that can be harmful.

• "a" and "an" are used with singular countable nouns, so they cannot be used with the uncountable noun "sugar" in this sentence.

• "the" is the definite article and refers to a specific item or previously mentioned noun; without such context, it is not suitable for a general health statement.

Examples: Sugar is bad for your health. | Some sugar in your diet can be harmful. | The sugar on the cake is too sweet.
