Marvin’s behavior at the party last night is fascinating in that there is no evidence that he drank the entire container of punch despite the fact that he was the only person known to have been by the punchbowl between the time it was filled and the time it was observed to be empty. If Marvin had drunk the entire bowl, then some of the punch would inevitably have spilled on the tile, but I examined the tile carefully and found no evidence of spilled punch. Thus Marvin must not have drunk the entire punchbowl.

Which of the following, if true, most strengthens the argument?

A. Most large drinks that have been imbibed at parties result in significant spillage.
B. The person examining the tile for evidence of spilled punch has been able to detect such evidence in considerably more obscure, hidden places.
C. Marvin’s behavior at the party was observed for the first time by the examiner.
D. Many of the other telltale signs of a punchbowl’s being consumed were found.
E. At certain raucous parties like the party in question, some punchbowls are merely thrown out the window as part of a prank.

OPTION A:- INCORRECT
This doesn't strengthen the argument because if true that most large drinks at parties result to significant spillage, the fact that there is no evidence of spillage opposes this option.

OPTION B:- CORRECT
If true that the person examining the tile can detect evidence in a considerably more obscure hidden places, it mean the claim and conclusion of the examiner is legit and reliable and in essence strengthens the argument.

OPTION C:- INCORRECT
The fact that Marvin's behavior was observed at the party by the examiner for the first time doesn't seen to strengthen the argument in anyways.

OPTION D:- INCORRECT
The fact that other evidences that the punch was consumed is found shows that the punch might have been consumed by Marvin and therefore weakens the argument because it opposes it.

OPTION E:- INCORRECT
If true that the punch bowl was thrown out of the window as some sort of prank, it shows support to the argument because it shows that Marvin didn't drink the whole bowl of punch but it doesn't account for Marvin behavior, so it doesn't strengthen the argument.
