Help the HR manager understand the company newsletter. Read the sentence below and choose the statement that correctly describes its meaning.

"The developers, who fixed the server crash, were given an extra week of vacation."

The correct answer is All the developers fixed the server crash and got extra vacation.

The commas make this a non-defining relative clause. This means the clause just adds extra, descriptive information about "the developers" as a whole group. It implies that all the developers fixed the crash and got the vacation!

If there were no commas ("The developers who fixed the server crash..."), it would be a defining relative clause, meaning only a specific subgroup of developers got the vacation.
