Question

complete the sentence with the best relative pronoun.

at the nelson-atkins museum in kansas city, missouri, artist robert morris created the glass labyrinth—a maze - like sculpture contains nearly one million pounds of plate glass.

Explanation:

To complete the sentence, we need a relative pronoun that introduces a relative clause modifying the noun "sculpture". The relative pronoun "that" or "which" can be used here. Since "sculpture" is a non - human noun and the clause is restrictive (providing essential information about the sculpture), "that" is a common choice. "Which" is also possible, but in restrictive relative clauses, "that" is often preferred, especially in American English.

Answer:

that (or which)
