解释中the summons required that be appear 的summons 什么意思啊，在这里作名词我只查到

n. 召唤,传唤,召集

Idiom

The verb require may be followed by an object (it required more time), a relative pronoun (the summons required that he appear), an infinitive (I am required to go), or an adverb (they are required now). This sentence uses the idiomatic construction require x to do y. Require is used transitively, taking a direct object, anyone, which must be followed by the infinitive to make. No other verb form is acceptable.

A     Requires must be followed by the infinitive to make, not the verb make

B     Requires must be completed by the infinitive, not a future tense verb

C     Correct. Requires is correctly completed in this sentence by the infinitive to make.

D     Requires must be followed by the infinitive to make, not the verb must make

E     Requires must be completed by to make, not must then make
