Jeremy was not one to (i) _________ his success, so his family was shocked when they finally discovered that their (ii) _________ son was a Rhodes Scholar.
You know that Jeremy is successful, but it takes his family a long time to “discover” his accomplishments. Thus, Jeremy does not brag — or even report the facts! To trumpet is to “talk loudly or report something to everyone.” In the second blank, only taciturn (quiet) works. Don’t be fooled by prodigal, which occurs in the expression “prodigal son,” but actually means “wasteful.” (The original prodigal son from the Bible ungratefully wasted his inheritance.)
