Choose the best alternative for the underlined part 12.
F. NO CHANGE G. Even in 1930; for example H. Even, in 1930 for example, J. Even in 1930, for example,
The best answer is J, which uses commas to set off the parenthetical (nonessential) element for example from the rest of the sentence. The other choices either use no punctuation or use punctuation incorrectly. Choice F creates confusion and ambiguity by allowing the nonessential element to blend into the sentence. Choice G uses a semicolon instead of a comma and does not set off for example from the rest of the sentence. Choice H does not correctly identify the nonessential element in the sentence.
