While researching a topic, a student has taken the following notes:

• • 2024: Spain and Portugal sponsored a workshop to address recent encounters between Iberian orcas and marine vessels off the Iberian Peninsula.

• • Many of the 637 documented incidents involved pods of orcas damaging vessels by ramming, nudging, or biting the rudders.

• • Studies of Iberian orcas suggest recent increases in tuna populations have reduced the time the orcas spend hunting by 99%.

• • Researchers believe this shift has increased the number of interactions between marine vessels and understimulated orcas.

• • The workshop advised mariners to avoid orcas pending further testing of the efficacy of TAST, a harmless acoustic deterrent.

The student wants to make and support a claim about Iberian orca behavior. Which choice most effectively uses relevant information from the notes to accomplish this goal?

• A.

  The recent destructive behavior of Iberian orcas may be the result of understimulation, given that orcas’ interactions with marine vessels have increased as the orcas have spent less time hunting.

• B.

  Tuna populations have increased by approximately 99% off the Iberian Peninsula due to changes in the hunting behavior of Iberian orcas.

• C.

  As supported by the workshop’s analysis of 637 encounters between vessels and Iberian orcas, TAST is a harmless and effective acoustic deterrent.

• D.

  In 2024, Spain and Portugal sponsored a workshop that addressed incidents where pods of Iberian orcas were ramming, nudging, or biting the rudders of vessels.
