It is widely known that oxidants are toxic in large amounts, and our cells naturally generate their own anti-oxidants to neutralize them. Accordingly it is advised that people boost the intake of antioxidants to counter the effects of toxic "reactive oxygen species," or ROS, the elevated levels of which are connected with various cancers. However, such advice may not have any substantial medical grounds as new research shows that tumor-promoting ROS are produced at cellular energy factories called mitochondria whereas supplements and dietary antioxidants tend to accumulate at scattered distant sites in the cell not connected with mitochondria at all.
In the argument above, the two bold-face portions play which of the following roles?
  • a)
    The first is a conclusion against the position taken by the argument; the second acts as evidence in support of that position.
  • b)
    The first is evidence that the argument disputes; the second is an observation that supports the main conclusion drawn by the argument.
  • c)
    The first acts as evidence against the position taken by the argument; the second acts as a reason in support of the position taken by the author.
  • d)
    The first is a conclusion that is disputed by the argument; the second is evidence that supports that conclusion.
  • e)
    The first is a conclusion that the argument as a whole disputes; the second is evidence that supports the position taken by the argument.

Argument Analysis
Pre-Thinking
Conclusion Clarification
Main Conclusion of the argument: “However, such advice may not have any substantial medical grounds”. Therefore, the main conclusion provides an explanation and a piece of evidence that opposes the advice mentioned in the previous statement.
Pre-Thinking Approach
The question requires us to identify the role played by the two bold face portions in the argument. To do so, we will examine the argument structure and the relationship of the bolded portions with respect to the main conclusion of the argument.
BF1 – As explained in the passage analysis, BF1 presents a third party’s conclusion, which is opposed by the main conclusion.
BF2 – It presents evidence to support the main conclusion.
With the above understanding, let us analyze the option statements.
Answer Choices
A
The first is a conclusion against the position taken by the argument; the second acts as evidence in support of that position.
Incorrect - 1st part wrong
The main conclusion opposes BF1, not the other way round. The description of BF2 is correct; BF2 acts as a piece of evidence to support the main conclusion – position taken by the argument, which is referred to as “that” position.
B
The first is evidence that the argument disputes; the second is an observation that supports the main conclusion drawn by the argument.
Incorrect - 1st part wrong
BF1 is not evidence. It is a claim that the argument disputes. BF2 can be called an observation/a piece of evidence that supports the main conclusion.
C
The first acts as evidence against the position taken by the argument; the second acts as a reason in support of the position taken by the author.
Incorrect - 1st part wrong
BF1 is not evidence/a fact. It is an opinion challenged by the main conclusion. The description of BF2 is correct.
D
The first is a conclusion that is disputed by the argument; the second is evidence that supports that conclusion.
Incorrect - 2nd part wrong
BF1 is a conclusion that the argument disputes. However, the description of the second part is incorrect; BF2 is evidence that supports the main conclusion which disputes the conclusion in BF1. Therefore, BF2 is evidence against that conclusion.
E
The first is a conclusion that the argument as a whole disputes; the second is evidence that supports the position taken by the argument. 
Correct
As discussed in the pre-thinking analysis, the description of both the parts is correct. BF1 is a conclusion that the argument challenges. BF2 is evidence that supports the main conclusion, the position taken by the argument.

A team of researchers has been able to successfully study the highly complex molecular structure of mitoribosomes, which are the ribosomes of mitochondria. Ribosomes are found in the cells of all living organisms, and they serve as a primary location for biological protein synthesis, but certain organisms such as fungi, plants, animals, and humans contain much more complex ribosomes than bacteria do. In organisms with complex cells, ribosomes can also be divided into two types: those in the cytosol -- which comprises the majority of the cell -- and those found in the mitochondria or power houses of cells. Mitochondria are found only in eukaryotes. Every ribosome consists of two subunits. The smaller subunit uses transfer ribonucleic acids to decode the genetic code, which is stored in the DNA, it receives in the form of messenger ribonucleic acids, while the larger subunit joins the amino acids delivered by the transfer ribonucleic acids together like a string of pearls.Since they are found only in small amounts and are difficult to isolate, mitochondrial ribosomes or mitoribosomes are particularly difficult to study. But because of the recent technical advances in cryo-electron microscopy and the development of direct electron detection cameras that can correct for specimen motion during the exposure, it recently became possible to capture images of biomolecules at a resolution high enough to capture the details, especially those of the peptidyl transferase centre (PTC).This research is of special importance to producing the right kind of antibiotics for humans. PTC is where the amino acid building blocks are combined, leading to protein synthesis. As per the researchers, this process of synthesizing proteins is medically relevant as the tunnel through which the proteins pass, after being synthesized, is a target for specific antibiotics. The antibiotic blocks the tunnel, preventing the proteins that have just been synthesized from leaving the tunnel. However, for an antibiotic to be used in humans, it must not attack human ribosomes and should inhibit protein synthesis only in the ribosomes of bacteria. The problem arises since mitochondrial ribosomes resemble those of bacteria, which is why certain antibiotics also interfere with mitoribosomes, possibly leading to serious side effects. The findings of the research will make it possible in the future to design antibiotics that inhibit only bacterial and not mitochondrial ribosomes, the one basic requirement for using them in clinical applications.The author is primarily concerned with
