### HideShow timer Statistics

Among 35-45 years old in Gowburg, some prefer music that was 20 years ago, whereas others prefer music that is popular today. Children and spouses of people who prefer music that was popular twenty years ago are themselves three times as likely as others in Gowburg to prefer music that was popular twenty years ago. Children of people who prefer music popular today are ten times more likely than others in Gowburg to prefer music that is popular today, whereas spouses of people who prefer music that is popular today are no more likely than other residents of Gowburg to prefer such music.

The information above provides most support for which of the following hypothesis?

A) Parents who prefer music that is popular today are more likely to have musical tastes in common with their children than with their spouses.
B) Unmarried adults are more likely to prefer music that was popular twenty years ago than music that is popular today.
C) Parents who do not have musical preferences are less likely than the general population to have spouses who have musical preferences.
D) Children of people who prefer music that was popular twenty years ago are not more likely than the general population to prefer music that was popular 20 years ago.
E) Between 10% and 30 % of children prefer either musical that is popular today or music that was popular twenty years ago.

This one seems to be easy as answer choices are spread far apart. I face difficulty with such questions though, request experts to review this question type and please provide some more examples of this kind and strategy to solve such question.
Time taken to interpret loads of info and then deciphering the answer choice appears very difficult to me.

Zarrolou has posted a perfect answer already. I just want to systemize the question in another way. Hope it helps.

GENERAL INFO:

First of all, this is “MUST BE TRUE” question. There are some important notes about it. If you follow this instruction properly, you just need under 2 minutes to solve this question.

First rule of thumb:NO NEW information accepted”.
Second rule: A correct answer MUST pass the “Fact test”.

There are ONLY 2 types of correct answer:
(1) Paraphrase (re-write parts of the stimulus in other way but keep the same meaning)
(2) Combination (combine two or more parts of the stimulus to make an inference)

ANALYZE THE STIMULUS:

Fact #1: Among 35-45 years olds in Gowburg, some (G1) prefer music-20 years ago, others (G2) prefer music-pop today.
Fact #2: Children and spouses of G1 are themselves three times as likely as others [general population] in Gowburg to prefer music that was popular twenty years ago.
Fact #3: Children of G2 are ten times more likely than others [general populations] in Gowburg to prefer music that is popular today
Fact #4: Spouses of G2 are no more likely than other residents of Gowburg to prefer such music.

A) Parents who prefer music that is popular today are more likely to have musical tastes in common with their children than with their spouses.
Correct. This is the combination of fact #2 and fact #3. If you still doubt about it, just leave it as contender, move quickly to other options to eliminate the WRONG answers. Please keep in mind, in CR eliminate wrong answers always is easier than determine the correct one.

B) Unmarried adults are more likely to prefer music that was popular twenty years ago than music that is popular today.

C) Parents who do not have musical preferences are less likely than the general population to have spouses who have musical preferences.
Wrong. Nothing about “people who do not have musical preferences”. Do not hesitate, eliminate it right away if you want to save time. Just stick to the facts: G1- people like old music + their children + spouses and G2-people like today pop music + their children + spouses.

D) Children of people who prefer music that was popular twenty years ago are not more likely than the general population to prefer music that was popular 20 years ago.
Wrong. D is a contradict option. D says: Children of G1 are not more likely than general population to prefer music 20 years ago. But fact #2 says: Children of G1 are 3 times more likely…….

E) Between 10% and 30 % of children prefer either musical that is popular today or music that was popular twenty years ago.
Wrong. Nothing about 10% and 30% because you DO NOT see any percentage info in the stimulus. ==> Out immediately.

TAKEAWAY:
In “Must be true” quesiton:
(1) NO new info accepted
(2) A correct answe MUST pass the fact test
(3) Eliminate a WRONG is easier than determine a CORRECT.

Hope it helps.

Among 35-45 years old in Gowburg, some prefer music that was 20 years ago, whereas others prefer music that is popular today. Children and spouses of people who prefer music that was popular twenty years ago are themselves three times as likely as others in Gowburg to prefer music that was popular twenty years ago. Children of people who prefer music popular today are ten times more likely than others in Gowburg to prefer music that is popular today, whereas spouses of people who prefer music that is popular today are no more likely than other residents of Gowburg to prefer such music.

The information above provides most support for which of the following hypothesis?

A) Parents who prefer music that is popular today are more likely to have musical tastes in common with their children than with their spouses.
CORRECT: Children are ten times more likely than others in Gowburg to prefer music that is popular today, whereas their spouses are no more likely to prefer such music.
B) Unmarried adults are more likely to prefer music that was popular twenty years ago than music that is popular today.
The text does not give us info about preferences of unmarried adults.
C) Parents who do not have musical preferences are less likely than the general population to have spouses who have musical preferences.
We have no info about both the general population and general musical preferences.
D) Children of people who prefer music that was popular twenty years ago are not more likely than the general population to prefer music that was popular 20 years ago.
No info about the general population.
E) Between 10% and 30 % of children prefer either musical that is popular today or music that was popular twenty years ago.
Once more we have no info about the general population.

In must be true question (and also in inference questions) the most important thing is to stick to the text: you know only what the text says, do not generalize and use only the info provided.

The information above provides most support for which of the following hypothesis?

In such questions, it is difficult to analyse the information as it may confuse you. The best way to deal with such questions is to use POE.

A) Parents who prefer music that is popular today are more likely to have musical tastes in common with their children than with their spouses. Language match. Keep it.

B) Unmarried adults are more likely to prefer music that was popular twenty years ago than music that is popular today. Not mentioned

C) Parents who do not have musical preferences are less likely than the general population to have spouses who have musical preferences. Parents who do not have musical preferences not mentioned

D) Children of people who prefer music that was popular twenty years ago are not more likely than the general population to prefer music that was popular 20 years ago. General Population not mentioned in this context

E) Between 10% and 30 % of children prefer either musical that is popular today or music that was popular twenty years ago. Percentage not mentioned
