Among small- to medium-sized marine mammals such as seals and dolphins, the longer an animal can stay submerged during a dive, the greater the depth the animal can reach. Dolphins can dive to greater depths than northern fur seals can, and elephant seals can stay submerged longer than Weddell seals can.
If the information above is accurate, then each of the following statements could be true EXCEPT:
Given D>N and E>W. But no relationship between two cases.A. Dolphins can dive to greater depths than Weddell seals can, but not to depths as great as elephant seals can.
D>W and E>D as per the choice..
Given is D>N and E>W. Possible E>D>N>W... could be trueB. Weddell seals can stay submerged longer than northern fur seals can, but dolphins can dive to greater depths than Weddell seals can.
W>N and D>W...
Possible that E>D>W>N...again could be trueC. Weddell seals can dive to greater depths than dolphins can and can stay submerged longer than northern fur seals can.
W>D and W>N
Possible that E>W>D>N... Could be trueD. Northern fur seals can stay submerged longer than elephant seals can, but Weddell seals can dive to greater depths than dolphins can.
N>E and W>D
Here N>E but D>N and E>W, so only possibility is D>N>E>W. But W can never be >D
Cannot be trueE. Northern fur seals can stay submerged longer than Weddell seals can, but elephant seals can dive to greater depths than northern fur seals.
N>W and E>N
E>D>N>W.. Could be trueD
