单选题
One purpose of the conferences was to
foster
a dialogue between opposing sides in the arms race, and the speakers often included scientists and government officials in charge of the unclear arms programs in their own countries.
【正确答案】
A
【答案解析】[解析] 句意：会议的目的是促使军备竞赛两方展开对话，而发言者通常包括两国负责不明确军事项目的科学家和政府官员。foster在句中指“促进；鼓励；培养”。start意为“开启”，start a dialogue指“开启对话”，与foster a dialogue表达意思相一致。bring up提出；养育。develop开发。involve包含，牵涉。
