Craft and Structure practice question

Text 1 Islands tend to produce dwarf versions of large mainland animals, such as the small elephants of ancient Sicily. Biologist Ren Halvorsen attributes this to food: with less to eat, smaller bodies survive. Text 2 Food limits matter, but the pattern also holds on islands rich in vegetation. What islands more reliably lack is predators. Without them, a large body offers no protection and costs energy, so size drifts downward over generations.

Which choice best describes the relationship between the two texts?

  1. A. Text 2 accepts that Text 1's explanation plays a part but proposes a different main cause.Correct
  2. B. Text 2 denies that island animals are ever smaller than mainland relatives.
  3. C. Text 2 provides the evidence for Halvorsen's food explanation.
  4. D. Text 2 argues that islands have more predators than mainlands.

Answer: A. Text 2 accepts that Text 1's explanation plays a part but proposes a different main cause.

'Food limits matter, but' — then predators as the more reliable cause.

Why the other answers are wrong

B. Text 2 denies that island animals are ever smaller than mainland relatives.
Text 2 says 'the pattern also holds', accepting dwarfing.
C. Text 2 provides the evidence for Halvorsen's food explanation.
Text 2 points to a case (rich islands) where the food explanation falls short.
D. Text 2 argues that islands have more predators than mainlands.
Text 2 says islands LACK predators.
