问题补充：

Students should be encouraged to their own opinions, right or wrong.

A. present; whether

B. compare; no matter

C. announce; no matter

D. remark; whether

答案：

(答案→)A. present; whether

B. compare; no matter

C. announce; no matter

D. remark; whether

解析：

试题分析:考查动词和连词。present“提出，呈现”；compare“比较”；announce“宣布”；remark“评论”。no matter后面需加疑问词，所以排除B、C选项。再根据词义判断A选项符合语境。句意：学生们应该被鼓励去提出他们自己的观点，不管是对是错。
