The sentence about the brain uses which word to introduce the clause 'controls language, memory, planning and our sense of time' ?

• A. which
• B. that
• C. who
• D. where

Answer: (A)

Think of how the clause relates to the noun before it. When you add extra information about a thing (not essential to identify it), you use a non-defining relative clause with which. The phrase “controls language, memory, planning and our sense of time” gives additional details about the brain rather than narrowing down which brain is being talked about, so it’s introduced by which (and it would be set off by commas in a sentence). Who is for people, where is for places, and that is typically used for defining information about things. So the word that fits best is which. For example: The brain, which controls language, memory, planning and our sense of time, is remarkable.
