单选题 President Bush came to his parent's century-old summer home on the Maine coast for a little relaxation, a distant cousin's wedding and some family time. However, several hundred anti-war demonstrators______on his visit.
【正确答案】 A
【答案解析】解析：句子大意为：布什总统前往缅因州其父母所在的享有百年历史的滨海度假村一作消遣，同时也是为了参加一个远房表弟的婚礼以及和家人团聚。然而，数百个反战游行示威者打乱了他的旅行计划。在给出的选项中：intruded“侵扰”，不及物动词；invade“入侵”，及物动词；intwine“缠绕”；inturn“内弯”。所以，正确答案是A。
