Because of rising temperatures in the tropical areas, many native birds, unable to tolerate the heat, are relocating to the northern, cooler regions. Pelicans, however, can tolerate high temperatures and hence, the tropical Pelican population is not expected to reduce.

Which one of the following statements, if true, would weaken the argument above?

A. The rising temperatures are affecting the northern, cooler regions too.
C. The plants on which the Pelicans feed are drying up because of the rising temperatures.
D. The mating season for Pelicans is in the summer which is elongated because of the rising temperatures.
E. Pelicans can survive in the northern, cooler regions just as easily as in the tropical regions.

Conclusion-the tropical Pelican population is not expected to reduce.
It will be weaken if found that some how population will be reduced.
Prethinking:- What if pelican is dependant on something,which will be reduced due to weather change. Then they have to migrate.

A. The rising temperatures are affecting the northern, cooler regions too.-Does not affect the conclusion
B. Pelicans are not found in the non-tropical regions.-Does not affect the conclusion
C. The plants on which the Pelicans feed are drying up because of the rising temperatures.-This is aligned to our prethinking
D. The mating season for Pelicans is in the summer which is elongated because of the rising temperatures.-Does not weakens the conclusion
E. Pelicans can survive in the northern, cooler regions just as easily as in the tropical regions.-Does not weakens the conclusion
