单选题 It is the community who should,in the main,determine whether police are to be involved in resolving community quarrels.
【正确答案】 D
【答案解析】解答本题的关键是要看出It is sb.who should do sth…的强调句结构,本句强调 主语。the community是集体名词,意为“共同体,群体”,可理解为“公众”。whether police are to be involved in resolving community quarrels作determine的宾语。
