问题详情：

 They promised to develop a software package by the end of this year, ______ they might have.

A. however difficult         B. how difficult

C. whatever difficulty      D. what difficulty

【回答】

 *：C

解析：题干的意思是：“他们承诺，无论可能有什么困难，到今年底都要开发出一个软件包”。本题是一个主从复合句，由句意“无论”可知是让步状语从句，从而排除选项B，D。从句中的关键词是实义动词have，用还原法，可知是短语have difficulty，所以从句为whatever difficulty they might have。如果选B，则从句要改为：however difficult it might be。

知识点：倒装与省略
