"Act well your part; there all honor lies."

- Alexander Pope

Directions to Solve

Each problem consists of three statements. Based on the first two statements, the third statement may be true, false, or uncertain.

During the past year, Josh saw more movies than Stephen.
Stephen saw fewer movies than Darren.
Darren saw more movies than Josh.
If the first two statements are true, the third statement is

[A].	true
[B].	false
[C].	uncertain

Answer: Option E

Explanation:

Because the first two sentences are true, both Josh and Darren saw more movies than Stephen. However, it is uncertain as to whether Darren saw more movies than Josh.

I cant understand about why the answer is uncertain it is just basic conditional statement such as a>b, b<c, c>a. Can any one explain?

Josh saw more movies than Stephen : J > S Stephen saw fewer movies than Darren : S < D Therefore : J > S < D Example values for J > S < D : 1. 50 > 10 < 40 2. 40 > 10 < 50 Given, Darren saw more movies than Josh = D > J. According to example 1 (50 > 10 < 40) 'D > J' is false. According to example 2 (40 > 10 < 50) 'D > J' is true. Therefore, we cannot say it true or false. That is why the result is 'uncertain'. Hope this help you. Have a nice day!

It's all about clear. And answer should be true but how come it's uncertain. Will anybody explain it.
