Q1对错判断

be based on（基于某事）用法正确；based on market research = 以市场调研为基础；thorough research conducted across twelve regions 具体化来源
Q2近义选词
选择最恰当的词填空：

Abase
Bfoundation
✓ 信任和相互尊重构成任何成功长期合作关系的基础，无论是商业还是个人生活。
form the foundation of（构成…的基础）是书面固定表达，用于抽象「奠基」概念；foundation 比 base 更强调「建立/奠定」的行为；form the base of 也可，但 foundation 更常用于抽象的核心价值
Q3搭配还原
选择正确的介词，完成句子：

Abased in
Bbased on
