B.No attendee who takes the festival seriously would fail to dress up as a ninja.

C.Anyone who is not dressed up as a ninja is not attending the festival

D.The festival organizers have instituted a ninja-themed dress code.

E.If an attendee is not dressed as a ninja, then that attendee will not be taken seriously by other attendees.

Please Explain why answer is not A or what is the clear difference between A and B

hi sajib,
lets see the choices..

A.Any attendee who dresses up as a ninja takes the festival seriously.
it does not talk of people who are not dressed up as ninjas, do they take the program seriously even when not in dress or they do not.... it just talks of one category of people , which is not being questioned in seriousness..

now B..
B.No attendee who takes the festival seriously would fail to dress up as a ninja.
look at it.. it talks of people of the category not attending in uniform that they are not serious and this is what we are looking for..
hope it helped...

ans B

hi,
In recent years, a village outside Osaka, Japan has taken to hosting a ninja festival, a celebration of Japan’s heritage that reflects on its feudal past while exalting its pop culture driven present. But clearly only children take this festival seriously, for they are the only attendees who bother to dress up as ninjas.
look at the coloured portion.. this is the argument

it states that children are the only serious attendee because they dress up like ninjas....
A tells us 'A.Any attendee who dresses up as a ninja takes the festival seriously.'.... if this is the assumption then the argument should have been But clearly children take this festival seriously, for they bother to dress up as ninjas....

however since the argument uses them as the only category that is serious, it means it is necessary to wear clothes as ninjas to be serious in program... or anyone not wearing the dress is not serious this is what B states

Hi sajib2126,

Negation technique is very helpful in solving 'assumption' type question.

Lets check option A first, and negate.

A. Any attendee who dresses up as a ninja takes the festival seriously.

Negate A - Any attendee who doesn't dress up as a ninja doesn't take the festival seriously.

It's the other way round -

If X, then Y ----> doesn't mean If Y, then X

If you take festival seriously, then dress up as ninja
If dressed up as Ninja, then you may or may not take the festival seriously.

Lets check option B, and negate.

B.No attendee who takes the festival seriously would fail to dress up as a ninja.

Negate B - Attendee who takes the festival seriously would dress up as a Ninja.

That is what clearly mentioned in the argument.

Hope this is clear now.

Correct me if I am wrong

This questions works on a simple rule

if P, then Q ==> ~Q --> ~P

For this condition ~P--> ~Q is always incorrect.

Here P is attendees who bother to dress up as ninjas and Q is Take the festival seriously.

A.Any attendee who dresses up as a ninja takes the festival seriously. : This is restatement, hence can't be Assumption.

B.No attendee who takes the festival seriously would fail to dress up as a ninja. Correct as per above rule.

C.Anyone who is not dressed up as a ninja is not attending the festival. : Incorrect as per above rule.

D.The festival organizers have instituted a ninja-themed dress code. : Irrelevant.

E.If an attendee is not dressed as a ninja, then that attendee will not be taken seriously by other attendees. : Same as C.

Negation technique should mean that negated statement invalidates the argument. I don't see how the negated B breaks down the argument. Wouldn't the negated statement for B be Attendee who fails to take the festival seriously dressed up as a ninja?

The argument says only children takes the festival seriously "since only they are bothered to dressed up as Ninja's".

It means the author is assuming that those you dressed up as Ninja's take the festival seriously.

Option B is saying the same thing "No attendee who takes the festival seriously would fail to dress up as a ninja.".

Let's negate this:

Some attendances who takes the festival seriously would fail to dress up as a ninja.

It means even if they are taking it seriously, they will fail to dress up as a Ninja. This means our assumption is broken because we clearly said dressing up as Ninja means taking the festival seriously. Hence, B is correct.
