Zoologist: As part of an experiment, several mature elephants were led to three enclosures- one that contained a distressed calf from the elephant’s herd, one that contained a distressed calf from a different herd, and one that was empty. It was observed that in the majority of cases, the elephants spent more time at enclosures with the calf from their herd than they did at enclosures with the calf from a different herd. This suggests that elephants are more motivated to care for members of their herd than for other elephants.
The zoologist's argument would be most strengthened if it were true that, in the experiment, the elephants led to the enclosures tended to spend more time at the enclosures when
A. they were encouraged by a familiar zookeeper than when they were encouraged by an unfamiliar zookeeper
B. the enclosure was empty than when the enclosure contained a distressed calf from a different herd
C. a distressed calf from the elephants’ herd was in the enclosure than when a distressed calf from the elephants’ herd was visible but outside the enclosure
D. a distressed calf in the enclosure appeared interested in the approaching elephants than when the calf ignored them
E. a distressed calf from a different herd appeared friendly toward elephants than when a distressed calf from a different herd displayed hostility
There are three enclosures - where
enclosure 1 contained a distressed calf which belonged to the same herd.
Enclosure 2 contained distressed calf which belongs to a different herd.
Enclosure 3 which was empty.
The experiment was repeated with multiple elephants and their calf’s and in majority of cases , the elephant responded to the distress call of the calf which belongs to its herd More than the distress call of a calf which belonged to other herd.
The experiment outcome : elephant is more motivated to care for members belonging to their herd than others.
Let’s look into the options individually,
A. they were encouraged by a familiar zookeeper than when they were encouraged by an unfamiliar zookeeper
The role of zookeeper is not related here. So irrelevant option. Eliminate.
B. the enclosure was empty than when the enclosure contained a distressed calf from a different herd
The comparison is made between empty and occupied enclosure from a different herd. But, elephants majority responded to distress call from their herd. This comparison does not strengthen . Hence, Eliminate.
C. a distressed calf from the elephants’ herd was in the enclosure than when a distressed calf from the elephants’ herd was visible but outside the enclosure
This clearly strengthens the phenomenon that elephants wish to interact with the distress call of the calf belonging to its herd. Here, the enclosure contained calf was approached by elephant when compared with the calf present beyond the enclosure but makes a distress call.
D. a distressed calf in the enclosure appeared interested in the approaching elephants than when the calf ignored them.
Calf approaching elephants is no way related to elephants behaviour of responding to distress call. Hence, eliminating it.
E. a distressed calf from a different herd appeared friendly toward elephants than when a distressed calf from a different herd displayed hostility
Variation of distress call of someone seeking help seems illogical. No where it’s mentioned as friendly and hostile call of calf. Hence, eliminate.
Option C
