ANALYZE THE STIMULUS:Fact 1: Each week, the Department of Defense sends food packages to its Navy Seals
Fact 2: On last Monday, ten shipments sent out were special ordered (SO)
Fact 3: On last Friday, all shipments sent out were granola bars and water (G&W)
Fact 4: No shipments sent out on weekend.
Fact 5: Nay seals received six shipments which included
only three G&WFrom the stimulus, we can deduce some notes:
Note #1: From fact 5,
Navy seals received at least two types of shipments – G&W shipment and Special ordered shipment.
Note #2: The stimulus does
NOT say Navy seals received ONLY G&W shipments and special shipments. They may receive OTHER type of shipment.
Note #3: Special ordered shipments MAY consist some G&W shipments.
ANALYZE EACH ANSWER:(A) At least one of the shipments sent to Covert Location #1 last week was specially ordered.
Wrong. From note 3: Probably, Navy seals received granola bars & water shipments and
OTHER type of shipment which was not special ordered.
(B) At least one of last week's specially ordered shipments did not consist of granola bars and water.
Wrong. We do not information that special ordered shipments consist of granola bars & water or not.
(C) At least one of the shipments sent to Covert Location #1 was not sent out on Monday of last week.
Wrong. Probably, the remain three shipments were special ordered shipments which were sent out on Monday.
(D) At least one of the shipments that were sent out on Friday of last week was sent to Covert Location #1
Wrong. TEMPTING. Probably, some of special ordered shipments consisted of Granola bars & water. Thus, we cannot assume that G&W shipments ONLY sent out on Friday.
(E) At least one of the shipments sent to Covert Location #1 last week was sent out before Friday.
Correct. ALWAYS TRUE. (1) If shipments sent out on days other than Friday, Monday for example,
did NOT consist any G&W shipment. ==> Navy seals must receive shipments sent out on Friday and other day (Because six shipments consisted two different types shipments) . Hence, E is correct.
(2) If shipments sent out on days other than Friday, Monday for example,
consisted some G&W shipments ==> Navy seals should receive at least one shipment sent out before Friday (because six shipments consisted two different types shipments). Hence, E is still correct.
Hope it helps.
Have a nice weekend guys
