What is the answer to the following:

Many ____ stomachs were often empty.

A refugees
B refugee's
C refugees'
D refugees's

Since this is a plural possessive, add an apostrophe after the 's." Refugees' is correct.

To determine the correct answer to the question, you need to consider the possessive form of the noun "refugees" in the given sentence: "Many ____ stomachs were often empty."

To find the correct possessive form, remember the rules for forming possessives. Typically, to make a singular noun possessive, an apostrophe and the letter "s" are added at the end. For plural nouns that already end in "s," only an apostrophe is added.

Now let's analyze the answer choices:

A) "Refugees": This option is the plural form of the noun, but it's missing the possessive form marker.

B) "Refugee's": This option is the singular possessive form of the noun. It indicates that the empty stomachs belong to one refugee, which does not match the context of the sentence.

C) "Refugees'": This option is the correct plural possessive form of the noun. It indicates that the empty stomachs belong to multiple refugees.

D) "Refugees's": This option is incorrect because it adds an extra "s" after the apostrophe, which is unnecessary.

Therefore, the correct answer is C) "Refugees'."
