Question

Select the correctly punctuated sentence. You are, if I'm not mistaken a good person, for this experiment. You are, if I'm not mistaken, a good person for this experiment.

Answer 1

Answer:

The second one:  You are, if I'm not mistaken, a good person for this experiment.

Explanation:

The first sentence, "You are, if I'm not mistaken a good person, for this experiment." does not have a comma after "mistaken", where there should be one. After "a good person", there should not be a comma.

Answer 2

Answer:

You are, if I'm not mistaken, a good person for this experiment.

Explanation:

this is because in the first one the comma in front of 'for this experiment' is unnecessary.
