Craft and Structure practice question

Because the fossil record for the period is so ____, scientists can only speculate about how the species behaved.

Which choice completes the text with the most logical and precise word or phrase?

  1. A. sparseCorrect
  2. B. abundant
  3. C. detailed
  4. D. reliable

Answer: A. sparse

'Because' links the blank to the consequence: scientists can only guess. That follows if the evidence is thin. 'Sparse' — scanty, few and far between — fits.

Why the other answers are wrong

B. abundant
An 'abundant' record would let scientists conclude, not speculate.
C. detailed
A 'detailed' record is the opposite of one that forces guesswork.
D. reliable
A 'reliable' record would support firm conclusions; the sentence says the opposite.
