The length of a bee’s tongue is proportional to the size of the bee, but it is also true that this proportion is inherited by each bee. Furthermore, the bee tongue is usually sized to match the depth of the flower it pollinates, making it possible for the bee to drink the nectar from it. Accordingly, there are both short-tongued and long-tongued bees that drink nectar only from flowers suited to their tongue size. Such bees are called specialists and since they depend on just a few flowers, they are quite vulnerable to changes in nature.

What could be inferred from statements above ?

(A) It is by studying the species of flower a bee pollinates that entomologists determine the exact body size of the bee and the species it belongs to.

(B) It is likely that a short tongued bee may have a problem drinking nectar from a flower that has a longer than average depth but a long tongued bee can easily sap the nectar of any kind of flower.

(C) Drastic changes in the flora of a land could affect the existence of certain bee species.

(D) The type of honey produced by the bees depends heavily on the flowers they pollinate.

(E) Across various bee species, the kind of flower a particular type of bee pollinates is exclusive from that pollinated by another type of bee.

giving my end of the thinking.

Premise 1: The length of a bee’s tongue is proportional to the size of the bee. so it goes with big size, big tongue.
premise 2: above property is inherited.
premise 3: also it goes with big tongue bee will go to big depth flower for pollination.

Inference question, lets try to eliminate choices by proving them wrong.

A: It is by studying the species of flower a bee pollinates that entomologists determine the exact body size of the bee and the species it belongs to. --- this is a long shot. also study of flower is not mentioned in premise.

B: It is likely that a short tongued bee may have a problem drinking nectar from a flower that has a longer than average depth but a long tongued bee can easily sap the nectar of any kind of flower. ---- This is likely true for normal scenario, but what if flower is very very small and only a very small bee can pollinate it while a very big size bee could not. many if are there and i don't have sufficient info for it. it is definitely a good contender for normal case.

C: Drastic changes in the flora of a land could affect the existence of certain bee species. --- so fact is specialists bees are dependent on specific flower. let just say suddenly flower size reduced to very small or species died. what will happen to bee. can it shift to other flowers. affect the existence is a very long shot.but if external info such as survival of the fittest is not used here then this choice can be true but in long shot. i still what to find a better choice.

D: The type of honey produced by the bees depends heavily on the flowers they pollinate. ---- i don't know any type of honey.

E: Across various bee species, the kind of flower a particular type of bee pollinates is exclusive from that pollinated by another type of bee. ---- we have no such info, one flower, multiple bees mapping is also possible.

C is best answer for sure.

Question stem is missing

It has to be : What could be inferred from statements above ?

C is answer as it is mentioned that tongue size if bee is somewhat based on type of flower it pollinates. Simply stating that Flora(plant) species have an impact on evolution of different tongue sizes in bees

This is a weird question because it says nothing about the specialist bees being a particular species, this also cannot be inferred as there is no prior mention of species. The stem only talks about tongues and size of bees

Thats the beauty of the question , read the last line carefully

Quote:

Hence, answer must be (C) Drastic changes in the flora of a land could affect the existence of certain bee species.
