Zoologist: Every domesticated large mammal species now in existence was domesticated thousands of years ago. Since those days, people undoubtedly tried innumerable times to domesticate each of the wild large mammal species that seemed worth domesticating. Clearly, therefore, most wild large mammal species in existence today either would be difficult to domesticate or would not be worth domesticating.

The zoologist’s argument requires the assumption that

(A) in spite of the difficulties encountered, at one time or another people have tried to domesticate each wild large mammal species
(B) it is not much easier today to domesticate wild large mammal species than it was in the past
(C) not all of the large mammal species that were domesticated in the past are still in existence
(D) the easier it is to domesticate a wild large mammal species, the more worthwhile it is to do so
(E) of all the domesticated large mammal species in existence today, the very first to be domesticated were the easiest to domesticate

Kudos! ;)

I would ask myself why is it difficult or not worthwhile to domesticate the large mammal species in existence today ?

They only option that really answers my question directly is option B .

Hope this answers your question :)

Premise: every domesticated large mammal species now in existence was domesticated thousands of years ago

Premise: since that time, people undoubtedly tried innumerable times to domesticate each of the wild large mammal species that seemed worth domesticating

Conclusion: thus, most wild large mammal species in existence today either would be difficult to domesticate or would not be worth domesticating

B is required for the conclusion to be valid. If you negate B, it becomes " it is much easier today to domesticate wild large mammal species than it was in the past" and is an objection to the conclusion/argument

Let me try to answer this in logical way:

Premise: every domesticated large mammal species now in existence was domesticated thousands of years ago

Premise: since that time, people undoubtedly tried innumerable times to domesticate each of the wild large mammal species that seemed worth domesticating

Conclusion: thus, most wild large mammal species in existence today either would be difficult to domesticate or would not be worth domesticating

As per me answer is B because earlier in the past they tried each wild animal to domestic that was worth of domesticating. So those who got domesticated are no longer wild animals, and those were difficult to domesticate or not worthy are still wild animal. That's why if we try to domesticate the left over(not yet domesticated) wild animals now are difficult ones or non worthy ones.

Source: LSAT


(A) in spite of the difficulties encountered, at one time or another people have tried to domesticate each wild large mammal species
Maybe, but unlikely. And it does not go as assumption.
(B) it is not much easier today to domesticate wild large mammal species than it was in the past
Yes. If it is not true, the conclusion will not stand
(C) not all of the large mammal species that were domesticated in the past are still in existence
It is likely true. But we have to find an assumption for "most wild large mammal species in existence today either would be difficult to domesticate or would not be worth domesticating". Existence of animals is important globaly, but not in this passge.
(D) the easier it is to domesticate a wild large mammal species, the more worthwhile it is to do so
Same as B.
(E) of all the domesticated large mammal species in existence today, the very first to be domesticated were the easiest to domesticate
Not important for us

todarmal option e is not a relevant assumption for the conclusion. even if you negate the option e it cannot break the conclusion of the passage. above, nikhilmadan87 post already explained the passage premises and conclusion beautifully with the connection to right option. hope you will clear with the concept.

Every domesticated large mammal species in existence today was domesticated thousands of years ago. That means there are some undomesticated large mammal species in existence today. Domesticating those large mammals required innumerable attempts. Conclusion of the argument is 'most large mammals in existence today are either would be difficult to domesticate or would not worth domesticating'.

Domesticating large mammals in existence today is difficult, that means, it requires innumerable attempts. Thousands of years ago, domesticating wild large mammals required innumerable attempts, now also, domesticating wild large mammals would require innumerable attempts. So, whether it is now or thousands of years ago, domesticating wild large mammals require innumerable attempts. That means, the effort to domesticate a wild large mammal is same (assumption of the argument).

Choice B says that domesticating a wild large mammal today is not much easier than it was in the past. That means, domesticating large mammals was difficult in the past, also it is difficult now. So, it is the correct answer.

Hi All

I got this one correct. But I have some doubt in eliminating option D.

Zoologist: Every domesticated large mammal species now in existence was domesticated thousands of years ago. Since those days, people undoubtedly tried innumerable times to domesticate each of the wild large mammal species that seemed worth domesticating. Clearly, therefore, most wild large mammal species in existence today either would be difficult to domesticate or would not be worth domesticating.

The zoologist’s argument requires the assumption that

(A) in spite of the difficulties encountered, at one time or another people have tried to domesticate each wild large mammal species
(B) it is not much easier today to domesticate wild large mammal species than it was in the past
(C) not all of the large mammal species that were domesticated in the past are still in existence
(D) the easier it is to domesticate a wild large mammal species, the more worthwhile it is to do so
(E) of all the domesticated large mammal species in existence today, the very first to be domesticated were the easiest to domesticate

Is D incorrect because it compares two things that are not relevant for comparison in this case. ??
How do we negate this.?
(the difficult it is to domesticate a wild large mammal species, the less worthwhile it becomes??? Is this correct?

Answer is B.
A conclusion about "today" is drawn based on practices followed 1000 years ago.
If wild large mammals species are easier to domesticate today, then they no longer come under the category of "difficult to domesticate". They would not come under a new category "wild large mammals that are easy to domesticate'.
Then the conclusion stating -> most wild large mammals are either ( difficult to domesticate OR not worth domesticating ),
would now become -> most wild large mammals are either ( easy to domesticate OR not worth domesticating ).

Our existing conclusion would fall apart.

Zoologist: Every domesticated large mammal species now in existence was domesticated thousands of years ago. Since those days, people undoubtedly tried innumerable times to domesticate each of the wild large mammal species that seemed worth domesticating. Clearly, therefore, most wild large mammal species in existence today either would be difficult to domesticate or would not be worth domesticating.

Type- assumption
conclusion - most wild large animals we see today either wouldn't be worth domesticating or would be too difficult to domesticate.

(A) in spite of the difficulties encountered, at one time or another people have tried to domesticate each wild large mammal species- incorrect, 'each' is a bit extreme, The author merely said that early humans tried to domesticate each wild mammal worth domesticating.
(B) it is not much easier today to domesticate wild large mammal species than it was in the past - Correct, If you negate (B), it says "it IS much easier today to domesticate wild large mammals" than it used to be. Is this an objection to the argument?
Yes. If it's much easier to domesticate wild mammals now, then some species deemed "too hard to domesticate" by early humans would now be viable candidates for domestication. That would go against the author's conclusion.
(C) not all of the large mammal species that were domesticated in the past are still in existence - incorrect, its wording is close to a legit assumption - the author is assuming that "all of the undomesticated large mammal species in existence today were in existence in the past". The author thinks that all the wild mammals we see nowadays have been evaluated by early humans
(D) the easier it is to domesticate a wild large mammal species, the more worthwhile it is to do so - incorrect, Too extreme. Be careful of "the more X, the more Y" type answers. The author doesn't need a relationship between "how easy" and "how worthwhile". He believes early humans evaluated "how worthwhile" and "how easy".
(E) of all the domesticated large mammal species in existence today, the very first to be domesticated were the easiest to domesticate - too extreme

Answer B
