Question

correct the text by inserting two commas. (note: in this skill, serial commas are not optional.)
smallpox is a dangerous disease true but should the only existing samples of the smallpox virus be destroyed?

Explanation:

To correct the text, we need to insert commas to properly structure the sentence. The phrase "Smallpox is a dangerous disease" is a statement, then "true" is a parenthetical or interjection, and "but" starts a new clause. So we insert commas after "disease" and after "true" to separate the parts of the sentence clearly.

Answer:

Smallpox is a dangerous disease, true, but should the only existing samples of the smallpox virus be destroyed?
