While researching a topic, a student has taken the following notes:
- • In a 2004 study, researchers Jorge E. López and C. Vaughan wanted to explore the effects of ingestion by bats on the germination of Piper sancti-felicis seeds in Costa Rica.
- • The team of researchers tested 125 Piper sancti-felicis seeds that had been ingested by chestnut short-tailed bats.
- • Of these, 82 seeds (66%) germinated. As a control, J.E. López and C. Vaughan tested 125 Piper sancti-felicis seeds that had not been ingested by chestnut short-tailed bats.
- • Of these, 88 seeds (70%) germinated.
The student wants to describe the study's research methodology. Which choice most effective y uses relevant information from the notes to accomplish this goal?
The team of researchers tested the germination of 125 Piper sancti-felicis seeds that had been ingested by chestnut short-tailed bats and 125 Piper sancti-felicis seeds that had not been ingested.
A
Research by J.E. López and C. Vaughan revealed that 82 of 125-that is, 66%-of the Piper sancti-felicis seeds that had been ingested by the bats germinated.
B
J.E. López and C. Vaughan wanted to explore the effects of chestnut short-tailed bats' ingestion on Piper sanctifelic seed germination.
C
In the study, a lower percentage of Piper sancti-felicis seeds ingested by bats germinated than those that had not been ingested by bats.
D
