The earliest known records of wartime activities detail the history of the use of carrier pigeons to communicate classified military information. Many people are not aware that the birds were also used extensively in the world wars of the twentieth century. Even today, their uncanny ability to fly home over great distances makes them valuable even to modern military units that need a way to deliver messages without the use of portable electronic devices whose signals can be intercepted.

The statements above, if true, best support which of the following conclusions?

The use of carrier pigeons is usually preferable to the use of portable electronic devices when a military unit needs a way to send classified military information.
The messages that carrier pigeons carry cannot be intercepted.
The use of carrier pigeons decreased once portable electronic devices became practical in warfare.
Carrier pigeons were used in warfare prior to the date of the earliest known record of wartime activity.
Carrier pigeons are still used extensively by modern military units.

From Kaplan

States that B is incorrect because birds can be shot and thus be interrupted.
But questions state "if true", meaning if it's true that birds cannot be shot down...

Isnt answer shouuld be B...!?

i can explain as why as B is not the answer
B says: The messages that carrier pigeons carry cannot be intercepted------>B is a huge deviation from the premise : Even today, their uncanny ability to fly home over great distances makes them valuable even to modern military units that need a way to deliver messages without the use of portable electronic devices whose signals can be intercepted---------> the fact that portable electronic devices are are being shunned because of the possibility that their signals might be intercepted is no testimony to the fact that messages that pigeons carry cannot be intercepted .

however i feel that even D cannot be the answer

I chose B as I found it the most convincing. Can't understand why D is the answer. Could someone care to explain?

The earliest known records of wartime activities detail the history of the use of carrier pigeons to communicate classified military information.

it states that earliest known records details the history..i.e history always states of the past.hence its D.
but tough one though.even i got it wrong.good 1.

KUDOS please if you find it helpful..

IMO C.
I am sure that the answer should be C as that can be inferred from the passage says. D doesnt make a logical conclusion. The fact that even the earliest records show the use of pigeons, its used to support the argument. It cant be the conclusion :S

Not sure why this is the correct answer.
D: Carrier pigeons were used in warfare prior to the date of the earliest known record of wartime activity.

IMO, this is not something that can be proved from the arg.
The earliest known records of wartime activities detail the history of the use of carrier pigeons to communicate classified military information.
P may/may not have been used as coi before the mentioned record. In such Qs correct shall be mild. Isn't that D is pretty strong in asserting?

I appreciate inputs from the members on this.

Although i went with B, i think i understand their method of using D and its a valid one. The entire paragraph is about the the bird being used in war times. The clause, 'even today', does show continuation of such use, hence the answer d. So we got confuse with the interception rather than the use of the birds

I think this is a good question.

Hard MBT-Inference arguments usually follow this pattern:

Passage provides with a lot of information. In this case:
- About the history of the use of carrier pigeons
- The pigeons in wars during the 20th century
- Modern military units
- Portable electronic devices.

But the answer will focus on just one portion of all this stuff. In this case, the first element. All the other stuff is just put there to pollute our minds.

In this type of questions you should ask yourself: "If all the elements in the passage are true, then which answer should be true a- regardless of how duh it sounds and b- regardless whether it refers to an important part of the passage or to a minor detail of the passage."

Answer choices are tricky as well. But D does the work.

The earliest known records of wartime activities detail the history of the use of carrier pigeons to communicate classified military information

So let´s say the earliest known records of wartime activities were in the year 1000 AD (just making this up... I have no idea). And the records discuss the history (some time in the past, before 1,000 AD: maybe 900 AD) of the use of carrier pigeons.

Answer choice D fairly rephrases this: Carrier pigeons were used in warfare prior to the date of the earliest known record of wartime activity.

Yes, it sounds pretty duh, but that´s how Inference questions work. Fair enough for me. Click and move on.

Kudos if it helped!

Responding to a pm:

You need to find the conclusion i.e. something which MUST BE TRUE according to the given argument.

Here is why (D) MUST BE TRUE:

(D) Carrier pigeons were used in warfare prior to the date of the earliest known record of wartime activity.

The earliest known records of wartime activities detail the history of the use of carrier pigeons to communicate classified military information.

The earliest know records tell about the "history" of the use of carrier pigeons. So carrier pigeons were used prior to the date of the "earliest known records". These records actually tell us about the history of the use of carrier pigeons for military information.

Here is why both (B) and (C) are incorrect.

(B) The messages that carrier pigeons carry cannot be intercepted.

The argument doesn't say that the pigeon msgs cannot be intercepted. It just says that pigeons are useful when electronic messages can be intercepted. Perhaps there is a much lower probability of pigeon messages getting intercepted. Perhaps, people do not try to intercept because they don't know that pigeons are still used and hence the pigeons are useful etc. The argument doesn't say that "messages CANNOT be intercepted". It just says that pigeons are useful when electronic messages can be intercepted.

(C) The use of carrier pigeons decreased once portable electronic devices became practical in warfare.

Again, we don't have enough information in the argument to say that. Perhaps the use of carrier pigeons stayed the same but portable electronic devices started getting used as well. Perhaps for a very long time after portable electronic devices became practical, they were not used because people were not comfortable with them and they till used pigeons. We don't know.

Hi, why not A.
Argument does mention that even today in some cases birds are used.
Thanks!

The argument states that pigeons are used even in modern military units to avoid messages getting lost in transit --> the use of portable electronic devices whose signals can be intercepted.

Option A states that:
The use of carrier pigeons is usually preferable to the use of portable electronic devices when a military unit needs a way to send classified military information.

This cannot be concluded from the argument. The military might still prefer devices when they need to send out information quickly. Only in one odd cases wherein the attack is possible, it prefers to use the pigeons over electronic signals. It can't be deduced that military will prefer pigeons in all cases to send secret messages to the destination. Way too extreme.

Answer is (D) even though I selected A too.....LOR as per me:

Q stem asks us to find a conclusion.....In such Q, it is always a Premise---->> Conclusion (only the information given in premise to be used to arrive at conclusion)


Premise 1: The earliest known records of wartime activities detail the history of the use of carrier pigeons to communicate classified military information.

Premise 2: Many people are not aware that the birds were also used extensively in the world wars of the twentieth century.

Sub premise 2 (supporting Premise 2): Even today, their uncanny ability to fly home over great distances makes them valuable even to modern military units that need a way to deliver messages without the use of portable electronic devices whose signals can be intercepted.


Premise 1 clearly states that earliest known record of wartime activities shows that CP were used to communicate MI....Wartime activities synonymous to warfare....And obviously if the Wartime records show something, then that something should have happened prior to recording such an instance (else how will you record it).

Premise 2/Sub premise in a way are supporting the Premise 1, that even later/today, CP is being used for Warfare.
