1.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.

2.Educator: Like any other difficult pursuit, music requires intense study and practice in order for one to become proficient. But many school music programs encourage only children who demonstrate early aptitude to continue studying music, while children who are not especially musical are directed towards other activities. Having learned to think of themselves as musically inept, these children do not devote any time to music and thus deprive themselves of the opportunity to develop a latent talent. The educator’s statements, if true, would best support which of the following conclusions?

A Music education should not devote special attention to talented students.

B Everyone has the potential to learn music.

C Talent is not always apparent at an early age.

D Children are particularly sensitive to criticism from adults.

E All children should study music.
