Strategy takeaway for CR?

Expert replies

Hi Experts,
What would be the strategy takeaway in this scenario?


In order to withstand tidal currents, juvenile horseshoe crabs frequently burrow in the sand. Such burrowing
discourages barnacles from clinging to their shells. When fully grown, however, the crabs can readily withstand
tidal currents without burrowing, and thus they acquire substantial populations of barnacles. Surprisingly, in
areas where tidal currents are very weak, juvenile horseshoe crabs are found not to have signi� cant barnacle
populations, even though they seldom burrow.
Which of the following, if true, most helps to explain the surprising � nding?
(A) Tidal currents do not themselves dislodge barnacles from the shells of horseshoe crabs.
(B) Barnacles most readily attach themselves to horseshoe crabs in areas where tidal currents are weakest.
(C) The strength of the tidal currents in a given location varies widely over the course of a day.
(D) A very large barnacle population can signi� cantly decrease the ability of a horseshoe crab to � nd food.
(E) Until they are fully grown, horseshoe crabs shed their shells and grow new ones several times a year.



We can solve a question if we are able to visualize or atleast understand what is the premise talking about. I wasn't able to see the relation between the barnacles and teh crabs and so couldn't get the answer. I had never heard of barnacles.

In such a scenario, if we don't understand the premise, I guess it isnt of any use reading the answers. We must let go our ego and just randomly chose a answer and move on, Time saved can be utilised on some other question .

What do u say?

The beginning said that burrowing prevents barnacles. Later the passage said that young crabs that don't burrow don't get barnacles.

Your question is why?

E

If they shed their shells regularly they won't have barnacles.

You have to find the logic and really the meaning of barnacles is irrelevant.

It is not just about barnacles.

If the premise or the argument is not clear( reasons may be because I have no idea what barnacles are or when the premise says : Such burrowing
discourages barnacles from clinging to their shells. I dint really know whom the pronoun their was referring to: barnacles or crabs. ) so when you get confused like this and dont know really understand the argument completely, it doesn't make sense reading answer choices .
