Julia has been a nurse all her life. She has spent her life caring for . . . . . . . . sick. A. a B. an C. the D. no article

The correct answer is D. no article.

The word “sick” is a non-count noun, which means it does not have a plural form and does not take an article. Other examples of non-count nouns are water, air, and love.

In the sentence “Julia has been a nurse all her life. She has spent her life caring for sick,” the word “sick” is used as a collective noun to refer to all people who are sick. In this case, it would be incorrect to use an article, such as “a” or “the.”

Here are some other examples of sentences using non-count nouns without articles:

• I need some water.
• The air is polluted.
• I have a lot of love for my family.
