Stimulus Summary

The star-nosed mole’s nose can detect electric fields, letting the moles hunt worms and insects.

Answer Anticipation

There’s a key word in the very short stimulus here - “enabling.” That’s a causal word, letting us know the means by which the moles hunt. If the mole’s nose’s ability to detect electric fields “enabl[es]” them to catch worms and insects, then worms and insects give off electric fields.

Answer choices

  1. A
    Both worms and insects Remaining source text redacted.
    Why choice A matches the stem
    Since the nose’s receptors that detect electric fields enable the moles to hunt worms and insects, it is very strongly supported that those worms and insects give off electric fields.
  2. B
    The star–nosed mole does Remaining source text redacted.
    Why choice B is not credited
    The nose tentacles are crucial for hunting, but that doesn’t mean that they moles don’t also use their eyes to hunt (crucial being necessary and important, but not necessarily the sole means). The stimulus also doesn’t discuss other things necessary for survival - maybe the moles use their eyesight to find shelter. This answer is out of scope.
  3. C
    The star–nosed mole does Remaining source text redacted.
    Why choice C is not credited
    The nose tentacles that detect electric fields enable the moles to find certain prey, but that doesn’t mean that their sense of smell isn’t used in hunting to find other prey, or for other reasons.
  4. D
    Only animals that hunt Remaining source text redacted.
    Why choice D is not credited
    The star-nosed mole’s nose tentacles allow the detection of electric fields, but the stimulus never states that these tentacles are the only sensory organ that can detect such fields, so this answer is unsupported.
  5. E
    The star–nosed mole does Remaining source text redacted.
    Why choice E is not credited
    There’s no discussion of the electric field of the mole itself, so this answer is out of scope.
