题目内容

Large quantities of information＿＿＿since then as to how the program has worked.

A．has been offered

B．were offered

C．have been offered

D．was offered

解析试题分析：句意：自从那时起，大量的关于这个项目怎么运作的信息已经被提供。和since then连用，应该用现在完成时，排除BD，因为主语是Large quantities of information，谓语和quantity的数保持一致，所以用复数，选C。
考点：考查主谓一致和时态
