Which statement about brackets is true?

i. brackets often come in threes or fives.

ii. brackets can indicate a change in verb tense.

iii. the phrase [sic] indicates an error in a quoted excerpt.

ii only
ii and iii
i and iii
i, ii, and iii

II and III.

Brackets can indicate a change in verb tense. The phrase [sic] indicates an error in a quoted excerpt. I is incorrect brackets must always come in pairs so that the beginning and end of what is bracketed is clear. Often when embedding a quotation into a sentence the author must change the verb tense to make the embedded quote grammatically correct with the rest of the sentence.

When changing any part of a quotation it is necessary to indicate that it has been altered by surrounding the change with brackets. Also, if there is an error in a quoted excerpt [sic] lets the reader know this error was made by the original author of the quote and not by the author who is using the quotation for support.
