Question Stats:

Neurobiologists have never questioned that axon malfunction plays a role in neurological disorders, but the nature of the relationship has been a matter of speculation. George Bartzokis’s neurological research at UCLA suggests that many previously poorly understood disorders such as Alzheimer’s disease may be explained by examining the role of the chemical compound myelin.

Myelin is produced by oligodendrocyte cells as a protective sheathing for axons within the nervous system. As humans mature and their neurochemistries grow more complex, oligodendrocyte cells produce increasing amounts of myelin to protect the Byzantine circuitry inside our nervous systems. An apt comparison may be to the plastic insulation around copper wires. Bereft of myelin, certain areas of the brain may be left vulnerable to short circuiting, resulting in such disorders as ADHD, schizophrenia, and autism.
Consider each of the choices separately and select all that apply.


It can be inferred from the passage that the author would be most likely to agree with which of the following statements regarding the role of myelin?

❑ The levels of myelin in the brain can contribute to the neurological health of individuals.

❑ Increasing the levels of myelin in the brain can reverse the effects of neurological damage.

❑ The levels of myelin in the brain are not fixed throughout the lifetime of an individual.

I solved the question in 2 m and 54 s. Is that time considered too much ?

Can I ask you what would it be a maximum time limit to solve it and in general, this type of questions? In your opinion. Thanks in advance!

Well, it really depends on your level of English as a whole. Your ability to grasp, dissect the argument, and to retain key information without getting lost in unuseful details in the passage.

There is not a fixed time but is more correct to talk about "average time". Because it also depends on the difficulty level of the reading itself.

If we would set the time: 1-3 minutes to reading the entire passage, which depends on the length, how many words it counts. One minute to answer a single question.

As it turns out, the more you grasp easily the passage, the more you will reply fast a question.

Hope this really helps you.

Regards

Do you spot why C is also correct ??

Ask for further assistance.

Clearly stated in second sentence of second paragraph;
As humans mature -> their neurochemistries grow more complex -> therefore it is changes throughout the lifetime of a human: option (C) is correct.
Try paraphrasing , e.g. (as in here) : not fixed throughout the lifetime = changes throughout the lifetime

I was very much tempted to consider answer B in question no 1. as the passage quotes

Bereft of myelin, certain areas of the brain may be left vulnerable to short circuiting, resulting in such disorders as ADHD, schizophrenia, and autism.

Lack of myelin causes such disorders, then could increase in the same alleviate the situation? How can we certainly say B is not an answer choice?
