B．marked
C．ignited
D．triggered
网考网参考答案：D
网考网解析：
[解析] 本题空格处是说引发一系列的争论。D项“triggered引发，触发”符合题意。如：a high-level meeting that triggered bitter bureaucratic debates．(一个引发了激烈的官僚政治论争的高级会议。)其他三项“contributed捐献；marked标记；ignited点火，使激动”都不正确。 document.getElementById("warp").style.display="none"; document.getElementById("content").style.display="block"; 查看试题解析出处>>
