- C, that Galileo built, which had a magnification of three times, helped
- Dthat Galileo built; which had a magnification of three times, helped
Cevap
The correct option is the one that leaves the sentence unchanged: 'that Galileo built, which had a magnification of three times, helped'.
The correct answer keeps the original punctuation. The clause 'that Galileo built' is restrictive because it is essential to identifying which telescope is being discussed, so it should not be preceded by a comma. The clause 'which had a magnification of three times' is nonrestrictive because it provides extra, nonessential details about the telescope, and therefore it must be set off with a pair of commas: one before 'which' and one after 'times'.
