I. Whenever some of the runners are leading off and all of

(A) expresses only a possibility. (E) apparently is definite from the given statement.

The pattern : some A and all of B = C

(A) speaks for the first part -- some A.
(E) speaks for the second part -- all of B. If only a part of B is true, then C is not true.

Some A and All B leads C
Some A and X leads to no C

We need to find X and hence it has to be related to infielders
Hence A, B out
C - Means "Some A and No B leads No C" may be correct but is extreme
D - Means "Some A and All B leads No C"
E - Means "Some A and some B (or not some B) leads No C"

D is wrong
Between C and E .... C is EXTREME

Hence E's my choice

To me it looks like a tough choice between C and E. I'll go with E and here's an attempt to explain.

I. SOME A leading off, ALL [color=red]B [/color]playing in = ALL C attepmting to bunt.
II. SOME A leading off = SOME C not attempting to bunt.

We need to deduce smth from both statements taken together.

A. - wrong, because we can deduce that from each statement taken separately. If some A ARE leading off, it means that some A are NOT leading off.

B. - wrong, because we can deduce that from statement II only. If some batters are NOT attempting to bunt, then some ARE attempting to bunt.

C. - wrong, because, like Srijay said, too EXTREME. If all B need to be playing in, for all C to attempt to bunt, then any lessening in the # of B playing in, would automatically lessen the # of B attempting to bunt. It doesn't have to be 'NO B playing in', therefore 'SOME C not attempting to bunt'. Although it could be valid as well.

D. - wrong, because "Whenever SOME of A are leading off, and ALL of B are playing in, then ALL of C are attempting to bunt". If D were true, then the result in statement II would equal the result of statement I (all batters attempting to bunt).

E. - is best.

Hi, Annie! Nice to see you!

As I can see, you are really strong in Verbal...

Don't hesitate to explore your weak points in Math as well. Finally, the more weak point in your Quant you will find, the greater your score will be.

Wow! You guys have been doing some serious posting! Too bad I couldn't visit the board during the weekend

You can either intuit the answer or get it this way:

I. Some Runners Lead Off & All Infielders Play In -> All Batters Bunt
II. Some Runners Lead Off & X -> Some Batters Not Bunt

Some Batters Not Bunt => Not All Batters Bunt.

Therefore,

II. Some Runners Lead Off & X => Not All Batters Bunt (We negate the conclusion of Statement I!)

If we deny the conclusion, the only thing we can deduce is that Not All Infielders Play In => "some of the infielders are not playing in."

On the E bandwagon.

E is my final answer.

For all batter to bunt, all fielders should play. So if some batters bunt then probably not all fielders play.

Great to stir up those discussions. OA is E
