Which grammatical structure completes the sentence about the jugglers?

• A. 'regardless of their'
• B. 'although their'
• C. 'despite their'
• D. 'in spite of these'

Answer: (A)

The idea being tested is how to express that an action happens no matter what condition or factor is involved. "Regardless of" means “no matter what,” and it is followed by a noun or noun phrase. In a sentence about jugglers, you want a setup that directly links to a noun describing a condition, so the flow stays smooth and concise. For example, the jugglers performed the act regardless of their nerves. This keeps the focus on the action continuing despite a factor.

The other options create a different grammatical shape. "Although" starts a clause and needs a full subject-verb clause afterward, which would shift the sentence into a comparison with a contrasting idea rather than state a condition the action ignores. "Despite" and "in spite of" are fine with a noun following, but they usually pair with a clearly stated noun phrase; they can feel clunkier or less natural here if the sentence is aiming for a single, streamlined modifier like "regardless of their."
