How quaint -- book references! :-)

I'd definitely check the Dictionary of American Biography.

I was thinking the same. Thanks!!

I think the last Americana Annual was published about 20 years ago. I threw out

my ancient set of Americana Encyclopedias when I got on the internet, about 15 years ago.

To locate the answer to the question, "What offices, elected or appointed, were held by John Quincy Adams before he became president?", one could use the source "D. Who's Who in America".

Explanation:

A. Dictionary of American Biography: While this source may provide biographical information about John Quincy Adams, it may not specifically mention the offices he held before becoming president.

B. Americana Annual: This source is an annual reference book that provides general information about various topics, but it may not contain detailed information about the offices held by John Quincy Adams.

C. The World Almanac and Book of Facts: Although this source may provide some information about John Quincy Adams, it primarily focuses on general information and may not provide specific details about the offices he held before becoming president.

D. Who's Who in America: This source is a biographical reference book that lists notable individuals and provides information about their achievements, including the offices they held. Therefore, it is more likely to contain the information about the offices held by John Quincy Adams before he became president.

Therefore, the correct answer is D. Who's Who in America.
