Question

He recommended that the goods ... be shipped at once.
A)might
B)should
C)had to
D)could
​

Answer 1

B) should.

The sentence is expressing a recommendation or advice, which is best conveyed using the modal verb "should". The other options don't fit the context, as "might" suggests uncertainty or possibility, "had to" implies obligation or necessity, and "could" implies ability or permission, which don't quite match the intended meaning.
