Hi Guys,

I have a confusion in a given condition,

If Q or D is selected , either R or S must be selected along with B.

Can anyone tell the representation for this ?

Thank you.

Danino has expressed dissatisfaction that many genetic studies have attributed the ‘spread of agriculture’ into the subcontinent to migrations. Just to be sure that no one thinks that the practice of agriculture is in the genes, I would like to point out that the spread of the technology of agriculture was associated with the movement of people; agriculturists who took the technology to new regions and taught it to the locals in the new region. Movement of people implies movement of genes. Some migrants ‘export’ their genes to a new region by taking spouses from the new region and producing children with them who stay in the new region. We can never be sure that the attribution of agriculture having been introduced to the Indian subcontinent by migrants is fully true. However, genetic data do support this model, especially of the spread of modern, organized agriculture.

Having said this, I must also emphasize, once again, that collection of more extensive data is always more helpful in understanding our past and of the spread of our inventions and innovations. A Y-chromosomal signature, haplogroup J, was shown to be associated with the spread of modern agriculture. This signature has its highest frequency in the Fertile Crescent region – the region comprising the present-day countries of Syria, Lebanon, Turkey – where the technology of modern agriculture was invented about 7,000–10,000 years ago. Collection of deeper data showed that this signature is quite heterogeneous and is composed of at least four sub-signatures, one of which – haplogroup J2b2 – is confined to the India–Pakistan region.

This sub-signature arose over 13,000 years ago and hence its introduction into India could not have been by migrants who introduced modern agriculture into India. We showed that the haplogroup J2b2 possibly arose in India, because the highest frequency of this haplogroup is found in India. We discovered multiple epicentres of this haplogroup in India and interestingly these epicentres neatly coincided with the seats of introduction of early forms of agriculture in India (as evidenced by the study of fossilized pollen grains by Fuller and his team). It is unlikely that haplogroup J arose independently multiple times in geographically separated places. It probably arose in an ancient population who had spread themselves in geographically separated regions and they invented rudimentary forms of agriculture independently in multiple geographical regions. However, it is notable that these early forms of agriculture remained largely confined to India and Pakistan region.

Question:

Danino believed that genetic studies, which “attributed the ‘spread of agriculture’ into the Indian subcontinent to migrations,” are:

1)incorrect because migrants did not introduce agriculture into the subcontinent.

true because it was indeed migrants who introduced agriculture into the subcontinent.

only partially correct as early forms of agriculture were indigenously developed in the subcontinent.

originally results of expert intuition but later validated by an improved ability to decipher evidence.

Need help in finding POV!

Correct Answer is 3 .

But I find AC 1 more suitable because 1st line of passage "Danino expressed dissatisfaction....."

Hi Guys,

Can you please help with this question ?

Either A’s faction or B’s faction, but not both, will win control of the government. If A’s faction wins, the nation will suffer economically. If B’s faction wins, the nation will suffer militarily.

Given the statements in the passage, which one of the following statements must be true?

(A) It is possible, but not certain, that the nation will neither suffer economically nor suffer militarily.

(B) If the nation suffers economically, it is certain that A’s faction has won control of the government.

(C) It is certain that the nation will suffer either economically or militarily, and also certain that it will not suffer both.

(D) If the nation suffers militarily, it is possible, but not certain, that B’s faction has won control of the government.

(E) If the nation suffers both economically and militarily, it is certain that neither A’s faction nor B’s has won control of the government.

I tried to apply the conditional logic but still i am not able to figure it out.

AW - A's faction wins

BW - B's faction wins

NSE- Nation suffers economically

NSM- Nation suffers militarily

ST(1) : AW->/BW

BW->/AW

ST(2) : AW->NSE

/NSE->/AW

BW->NSM

/NSM->/BW

I am not able to derive D (Right AC) from this logical conditionals.

I hope it is rephrased correctly.

Thanks.

Hi Guys,

I am stuck in parsing a sentence. I can't understand its meaning.

Here is the passage..

The ways by which you may get money almost without exception lead downward. To have

done anything by which you earned money merely is to have been truly idle or worse. If the

laborer gets no more than the wages which his employer pays him, he is cheated, he cheats

himself. If you would get money as a writer or lecturer, you must be popular, which is to go down

perpendicularly.

This line is taken Life without principles by Henry David.

Please help.TIA.

Hi Guys,

Differences between these with examples or any Video explanation?

Thanks in Advance. :)

Hi 7Sages,

I am facing a bit difficulty in dealing with the ACs of the MSS type of questions.

I want to ask about the best way to deal with these ACs.

When you go through each of the ACs, what do you try to do just after reading it?

Do you try to find reasons as to why that AC might be wrong ie Like trying to find a flaw which might occur here? Finding a subtle flaw is bit of a problem on my part. I am lacking in that respect.

Or Do you try to support the AC and try to find possible reasons how the AC can be the conclusion supported by the premises given in the question?

Thanks and Regards :)

Hi 7Sages,

I have a confusion in representing "if then must" conditions.

Suppose there is a sentence given as :

If N is not selected then T must be selected .

So, is the representation like this?

not N -> T

contrapositive is

not T -> N

If here, N is satisfied then does the rule drops away and does T becomes a floater ?

Since there is a 'must' keyword involved..I am confused.

Please clarify this.

Thank you.

Hello Sages,

I need your advice in logic games. For solving miscellaneous games, what should be the ideal approach? Since those games don't fall into a specified category , I don't know what the starting point should be . While practicing such games , should i spend as much time as possible (may be like 2-3 hrs) to first crack the game on my own instead of trying for 20 mins and then move on to watching the solution.My approach to solve a foreign setup should be able improve on its own as there is no specified way to deal with such games so I am trying in all possible ways to improve that . I am not sure if that is a good way to deal with foreign games. Am i trying the misc games the right way?Thanks.

Hi Sages,

I have a doubt regarding the order in which we should drill reading comprehension passages. Should we segregate easy, medium,hard passages from PT 1-35 ? Then first drill all the easy passages then move on to the medium level passages then finally take up hard passages ?What can be pros and cons of such a order? Pls advice. Thanks.
