(A) At least one of the shipments sent to Covert Location #1 last week was specially ordered. WRONG: Total six were sent to Location#1 out of which three contained Granola water. Rest three could contain anything other than specially ordered shipments that was sent last week . (B) At least one of last week's specially ordered shipments did not consist of granola bars and water. WRONG: Not Sure. Nothing can be inferred about the contents of the specially ordered shipments from the information given in passage. (C) At least one of the shipments sent to Covert Location #1 was not sent out on Monday of last week. WRONG: Since we do not know contents of rest of three shipments sent to Loc#1 and that of shipments sent on Monday, we can not correlate these two shipments. (D) At least one of the shipments that were sent out on Friday of last week was sent to Covert Location #1 WRONG: As we do not have information about the shipments sent throughout the week and those sent on Monday, we can not be sure whether the shipments sent on Friday were sent to Loc#1 or somewhere else as shipments sent to Loc#1 could have been sent on some other day. (E) At least one of the shipments sent to Covert Location #1 last week was sent out before Friday. CORRECT: As all the shipments sent on FRIDAY contained Granola bars and water and three of the shipments received at Loc#1 were not Granola bars and water, they must have been received on some other day. +1 kudos if the reply helped

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&W

From 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

danzig · Answer

+1 E

Three of the packages didn't contain granola bars and water, so they were not sent on Friday. Also, there were not shipments on Saturday and Sunday.

Therefore, the other three shipments were sent before friday.

What is the use of these kind of questions?

It is almost an EXACT copy of an official question!

Paris75 · Answer

OMG, this is a tricky question!

The main idea here is that the Covert Location #1  DID NOT ONLY RECEIVE PACKAGE ON MONDAY AND FRIDAY !

they could have received packages on thursday for example!

Which makes E totally logical!

Really tricky one here!

andy2whang · Answer

Dear,
So, this question is based on the assumption that packages could be sent between monday and friday?
The stimulus states that "Each week, the Department of Defense sends food packages to its Navy Seals training in a covert operation" and this automatically makes me think that they send once a week. 
For native english speakers, would they understand that multiple shipments could happen with this statement?

Thanks
Regards
Andy

v12345 · Answer

ya, I think the packages could be sent on any day between Monday to Friday (not on Saturday and Sunday - clearly mentioned)
i.e. they can be sent on Tuesday, Wednesday and Friday also

and by using this approach we can easily reach to the answer  E

Kudos if you like explanation

National Defense Coordinator:

Each week, the Department of Defense sends food packages to its Navy Seals training in a covert operation.

The  ten specially ordered shipments  sent out last week were sent out on  Monday .
Last week, all of the shipments that were sent out on  Friday  consisted  entirely of granola bars and water .

On  Saturday and Sunday, no shipments  were sent.

Six shipments  were sent to Navy Seals training in Covert Location #1, only three of which consisted of  granola bars and water.

If the shipping clerk's statements are true, which of the following must also be true?

(A) At least one of the shipments sent to Covert Location #1 last week was specially ordered.
 The ten specially ordered shipments sent out last week were sent out on Monday in covert operation. but we are not sure whether they are sent to location 1.

(B) At least one of last week's specially ordered shipments did not consist of granola bars and water.
 we re not sure what specially ordered shipments contained. We cant assure either they did or did not consist granola bars.

(C) At least one of the shipments sent to Covert Location #1 was not sent out on Monday of last week.
 (we know that 10 special shipments are sent on Monday although we are not sure that they are sent to location 1, we cant deny the possibility as well and 
only 3 of shipments in location 1 are granola bars & water we are not sure about other three and those may be one of the 10 special shipments sent on Monday. Hence we cannot infer this option.)

(D) At least one of the shipments that were sent out on Friday of last week was sent to Covert Location #1
 (We know that Friday shipments consisted of only granola bars but we cannot deny that they were not sent on other days from Mon-Thu and it is possible that 3 granola bars & water shipments may have been sent from Mon-Thu and hence we cannot infer this option.)

(E) At least one of the shipments sent to Covert Location #1 last week was sent out before Friday.
 On Friday all the shipments are of Granola bars & water and we have only 3 shipments of the same on Covert location #1.
3 more other shipments whatever they might consist of either special ordered or something else must come before Friday.

rsaahil90 · Answer

One doubt I had here: There is no mention that the packages sent on Monday, Tuesday, Wednesday or Thursday cannot contain Granola bars and water. Given this, how can we still conclude that E is an answer?

Thanks :roll:

Nevernevergiveup · Answer

On Friday all the shipments are of Granola bars & water Covert location #1 we have only 6 shipments in total only 3 of the them are of granola bars & water 3 more other shipments whatever they might consist of either special ordered or something else must come before Friday. you are right that it is not mentioned whether packages sent on Monday, Tuesday, Wednesday or Thursday can or cannot contain Granola bars and water. but it is definitely not on Friday(since on Friday all the shipments are of Granola bars & water ) Saturday and Sunday as mentioned in the argument. so we have to or can infer that the other 3 must have arrived on Mon-Thu anytime. I hope this helps

deepthij · Answer

Hi,

Have this question:

When the days mentioned in the argument are Mon, Fri, Sat and Sun can we make assumptions about other days?
For Inference type of questions aren't we supposed to stick with the info provided in the argument and not think out of it?
I feel considering other days would be Out of scope.
A little help in understanding this Pls.

Hello
I don't understand why B is wrong?
Let's say only 2 shipments were sent out on Friday, which consisted of only granola bars and water, then 1 shipment is remaining. There is a possibility that this remaining shipment is sent on Monday. So Out of 10, 9 specially ordered shipments sent on Monday will not consist of Granola Bars and water. Wouldn't that make Option B correct?
Or is it that Specially Ordered shipments are a different set from "Granola Bars and Water" shipment? Even if that were true, wouldn't B still hold?
Or is it that Specially Ordered shipments weren't sent to Covert Location #1 at all?
Thanks and Regards

Doer01 · Answer

Dept. sends food packages to seals on training every week.
Special shipment — Monday 
Only granolas and water shipment — Friday
Covert location 1 got 6 shipments. 3 out of six had granolas and water. Here, “entirely” is not mentioned. It might play a role while POE

ThisIsWater · Answer

B is also a correct option, since 3 didn't have granola so they were sent on Monday which implies option B
