Answer:
A star's gases' can burn for a long time
Explanation:
The word marked in bold in the sentence above is the word that has an error. The correct thing would be to write the word "gases" without using the apostrophe (') after the last "S", since the apostrophe is used to cause the impression of possession and it has already been used, correctly in the word "Star's".
Actually there are some exceptions in some cases though: a/an
example: "not only is there 3 species, but there is a 4th specimen."
