A certain medication used to treat migraine headaches acts by blocking pain receptors in the
brain. When a person takes the medication within one hour after ingesting grapefruit or
grapefruit juice, however, the effectiveness of the medication is significantly diminished.
Researchers have determined that the grapefruit contains a compound that alters the shape of
the pain receptors, with the result that the medication can no longer bind with them
completely. Which of the following conclusions could be most properly drawn from the
information given above?
A) If one takes the medication more than an hour after ingesting grapefruit, its effectiveness is
not diminished.
b) Ingesting grapefruit after taking the medication does not diminish the effectiveness of the
medication.
c) There is only one type of pain receptor in the brain.
d) The medication is fully effective only when it properly binds with its target pain receptors.
e) It is not possible to design a medication for migraine headaches that can bond with the
altered receptors.

Option A - INCORRECT.
This option is not describing the study in the right matter at which it is shown in the question. Rather, study shows that if the medication is taken after one hour of ingesting grapefruit then the effectiveness of the medication is significantly diminished.
In Option B - INCORRECT.
Since the intake of grapefruit generally diminishes the intake of the medication and alters the shape of the pain receptors due to the compound contained in it, then the time at which it was taken is of no use, cos it will still affect the effectiveness of the medication.
Option C - INCORRECT.
This fact was not stated in the research study in the speakers speech so makes this option invalid.
Option D - CORRECT.
This statement seeks to be more explanatory, and in line with the researchers conclusion. The researcher study shows that the medication is fully effective only when it binds with its target brain receptors without the intake of grapefruits which can cause a diminish in the effectiveness of the medication.
Option E - INCORRECT.
This option is not suitable as a summary of the researchers finding. The researchers summary only shows that there is a medication for migraines headaches only if there is no intake of grapefruit which can lower the effectiveness of the medication.
