Concept:Identify the words that are misplaced and need to be swapped to make the sentence grammatically and logically correct.
Explanation:The original sentence is: Albert Einstein’s intelligence (A) left behind a legacy (B) of knowledge that understand (C) physics and how we changed (D) gravity.
The words
understand (C) and
changed (D) are in the wrong positions.
The verb after
that should be
changed, because the legacy changed physics.
The verb after
we should be
understand, because we understand gravity.
Therefore, C and D must be interchanged.
The correct sentence becomes: Albert Einstein’s intelligence left behind a legacy of knowledge that
changed physics and how we
understand gravity.
This matches the option C-D.
Answer:Correct arrangement: C-D
