Hi Mechmeera,

Q4 is an inference question hence we will have to infer on data mentioned in the passage..(not explicitly mentioned).

However, "Today, few scientists challenge not only the link between birds and reptiles in general" in first para rewrites the same thing as option C in other words.

Per option D, Thomas believed in convergent evolution. Kindly note that nothing has been mentioned about Thomas's perception of evolution. In the last para, the author says that " This would certainly not be the first case of what is known as convergent evolution".

Hence D can be eliminated.

Regards,
Dom.

4. Which of the following can be inferred from the passage?

(A) All adult coelurosaurs possessed feathers.
ALL possessed feathers? Can't say for sure: Eliminate
(B) Coelurosaurs who did not need feathers for warmth or mating rituals
shed those feathers for scales.
May Be
(C) Scientists have reached a consensus that certain birds and dinosaurs
are evolutionarily linked.
Proof: Today, few scientists challenge not only the link between birds and reptiles in general, but between birds and theropods, a group of bipedal saurischian dinosaurs.
YES! The proof lies here : Today, [b]few scientists challenge
not only the link between birds and reptiles in general, but between birds and theropods, a group of bipedal saurischian dinosaurs.
[/b]
(D) Thomas Henry Huxley believed in the idea of convergent evolution.
Maybe
(E) Coeulurosaurs that did not have feathers instead had scales. Maybe

The key to doing well on an inference question to is to ensure that the answer statement is 100% true ALL THE TIME!
Avoid answer options that are MAYBEs!


Hope that helps!

the passage says few scientists challenge and then goes on to explain different theories possible for the similarities and ends with a note calling for more insights.
How can we then say scientists have reached a consensus. Had the option said few scientists it would have been correct

(B) has not been shown to apply to humans
(C) was not always thought to apply to birds and coelurosaurs
(D) was first noticed by Thomas Henry Huxley
(E) explains why some dinosaurs developed feathers for warmth

Please explain how we can lead to the right answer from the passage.


Whats the OA for this? IMO A.

IMO answer to the new question should be C

Option A seems incorrect as it says " common trait between birds and other animals " it does NOT say " Between birds and dinosaurs or between birds and coelurosaurs"

Had option A been "had not been thought to apply to a common trait found in birds and dinosaurs prior to the discovery of the Juravenator fossil" it could have been correct IMO.

I do not agree with the Question 3: in the passage, it is clearly stated that "feathers were replaced by scales because the feathers were not needed for". This clearly implies that: 1. There were feathers 2. They were no longer useful 3. They evolved to scales in other words: Scales evolved from feathers.

However, in the answer choice, it states that it is feathers that "might have evolved from the scales". X->Y is not same as X<-Y

Although I don't like this answer choice, B should be the answer
Because if there is at least 1 dinosaur with no feathers, this statement is true.

A more fundamentally profound alternative is that, contrary to conventional scientific thought , birds and feathered dinosaurs developed feathers independently of each other rather than from a common ancestor.


Experts, helps us out here. Can't understand the answer to Q3. Thanks!

3. According to the passage, feathers on dinosaurs .
(A) were not used for flight - NO! We don't know this for sure
(B) were not always present at birth NO! We don't know this for sure
(C) were first noted by Huxley NO! the passage never says that it was FIRST noted by Huxley
(D) might have evolved from scales Perhaps: scope is her - "One possibility is that, in some creatures, feathers were replaced by scales because the feathers were not needed for warmth, recognition of family members, or mating rituals—uses that feathers were thought to have had for dinosaurs that did not fly." - [color=#ff00ff]Isnt the passage saying the opposite, if at all scales could have evolved from feathers not the other way round. Please let me know if i am missing something. Thanks!
(E) were a characteristic of all coelurosaurs [b] ALL coelurosaurs? we don't know for sure


Option D therefore is the most reasonable response
