Can anybody provide explanations for the following? Tks in advance.Lw

1)When people predict that certain result will not take place unless a certain action is taken, they believe that they have learned that the prediction is correct when the action is taken and the result occurs. On reflection, however, it often becomes clear that the result admits of more than one interpretation.

Which of the following, if true, best supports the claims above?
(A) Judging the success of an action requires specifying the goal of the action.
(B) Judging which action to take after a prediction is made requires knowing about other actions that have been successful in similar past situations.
(C) Learning whether a certain predictive strategy is good requires knowing the result using that strategy through several trials.
(D) Distinguishing a correct prediction and effective action from an incorrect prediction and ineffective action is often impossible.
(E) Making a successful prediction requires knowing the facts about the context of that prediction.

2)The fact that several of the largest senior citizens’ organizations are constituted almost exclusively of middle-class elderly people has led critics to question the seriousness of those organizations’ commitment to speaking out on behalf of the needs of economically disadvantaged elderly people.

Which of the following generalizations, if true, would help to substantiate the criticism implicit in the statement above?
(A) The ideology of an organization tends reflect the traditional political climate of its locale.
(B) The needs of disadvantaged elderly people differ in some ways from those of other disadvantaged groups within contemporary society.
(C) Organized groups are better able to publicize their problems and seek redress than individuals acting alone.
(D) Middle-class elderly people are more likely to join organizations than are economically disadvantaged elderly people.
(E) People usually join organizations whose purpose is to further the economic, political, or social interests of their members.

3) A violin constructed to have improved sound would sound different from the best-sounding existing violins.
To professional violinists, a violin that sounds different from the best-sounding existing violins sounds less like a violin and therefore worse than the best-sounding existing violins.
Professional violinists are the only accepted judges of the sound quality of violins.

Which one would be the best supported by those statements?

(A) Only amateur violinists should be asked to judge the sound quality of newly constructed violins.
(B) Professional violinists supervise the construction of violins.
(C) The best-sounding existing violins have been in existence for several centuries. (asumir de mas, no dice que tengas varios siglos)
(D) It is currently impossible to construct a violin that the only accepted judges will evaluate as having improved sound.
(E) It is possible to construct a violin that sounds better than the best-sounding existing violins to everyone but professional violinists.

IMO B, E, E
1. B: I'm not sure, looking for explanations.

2. (A) The ideology of an organization tends reflect the traditional political climate of its locale.
…polity is not concern
(B) The needs of disadvantaged elderly people differ in some ways from those of other disadvantaged groups within contemporary society. other groups are out
(C) Organized groups are better able to publicize their problems and seek redress than individuals acting alone. …but no info about Class
(D) Middle-class elderly people are more likely to join organizations than are economically disadvantaged elderly people. weaken the criticism
(E) People usually join organizations whose purpose is to further the economic, political, or social interests of their members. my choice

3.(A) Only amateur violinists should be asked to judge the sound quality of newly constructed violins. …we are accepting Professional violinists only
(B) Professional violinists supervise the construction of violins. they are the judges not supervisor
(C) The best-sounding existing violins have been in existence for several centuries. (asumir de mas, no dice que tengas varios siglos) May be true but out of scope
(D) It is currently impossible to construct a violin that the only accepted judges will evaluate as having improved sound. We have already done that
(E) It is possible to construct a violin that sounds better than the best-sounding existing violins to everyone but professional violinists. My choice
