问题 Great efforts to increase wheat production must be made if bread shortages________avoided.

选项 A、will be
B、can be
C、are to be
D、were to be

答案 C

解析要避免面包短缺，就必须大力增加小麦的产量。动词时态题。if引导一个条件状语从句，主句用的是“情态动词must+动词原形”，表示“必须要做”，说明是将来的行动。if引导的条件状语从句中，用一般现在时表将来，所以A项选项不能选；B项选项用的情态动词can，不合题意；D项选项用了be动词的过去式，时态错误；只有C项用了be to do结构，表示将来，含有“按计划，必须”的意思，故C项为正确答案。
