It is theoretically possible that bacteria developed on Venus early in its history and that some were carried to Earth by a meteorite. However, strains of bacteria from different planets would probably have substantial differences in protein structure that would persist over time, and no two bacterial strains on Earth are different enough to have arisen on different planets. So, even if bacteria did arrive on Earth from Venus, they must have died out. 
The argument is most vulnerable to which of the following criticisms?
  • a)
    It fails to establish whether bacteria actually developed on Venus
  • b)
    It fails to establish how likely it is that Venusian bacteria were transported to Earth
  • c)
    ​It fails to consider whether all bacteria now on Earth could have arisen from transported Venusian bacteria
  • d)
    It fails to consider whether there were means other than meteorites by which Venusian bacteria could have been carried to Earth
Correct answer is option 'C'. Can you explain this answer?
Verified Answer
It is theoretically possible that bacteria developed on Venusearly in ...
The question asks which of the statements given in the options can weaken the argument put by the author that all bacteria from Venus must have died out.
The passage states that since there is a single strain of bacteria which exists on the Earth, they all must be belonging to the Earth or let's say a single planet. But here the author does not take into consideration (as can be argued from his theory) the fact that may be all the bacteria came from Venus and there are none which originally belong to the Earth. So this criticism as mentioned in option 3 makes the argument of the author vulnerable. 
Options 1, 2 and 4 are completely irrelevant criticisms as they do not address the main argument. The argument claims that if there were Venusian bacteria on Earth, then they must have died out by now. Whether there are bacteria originally from Earth that have also disappeared from Earth is irrelevant to the question and has no effect on the given argument.

It is theoretically possible that bacteria developed on Venusearly in ...
The argument is most vulnerable to which of the following criticisms?

Correct Answer: C. It fails to consider whether all bacteria now on Earth could have arisen from transported Venusian bacteria

Explanation:
The argument in the passage discusses the possibility of bacteria developing on Venus and being transported to Earth by a meteorite. However, it states that strains of bacteria from different planets would have substantial differences in protein structure that would persist over time. It also mentions that no two bacterial strains on Earth are different enough to have arisen on different planets. Based on this information, the argument concludes that even if bacteria did arrive on Earth from Venus, they must have died out.

Key Points:
- Bacteria developed on Venus and were transported to Earth by a meteorite
- Strains of bacteria from different planets would have substantial differences in protein structure
- No two bacterial strains on Earth are different enough to have arisen on different planets
- Even if bacteria arrived on Earth from Venus, they must have died out

Analysis of the Correct Answer:
The correct answer is option C, which states that the argument fails to consider whether all bacteria now on Earth could have arisen from transported Venusian bacteria. This criticism highlights a potential flaw in the argument. The argument assumes that if bacteria from Venus arrived on Earth, they would have died out. However, it does not consider the possibility that the bacteria from Venus may have evolved and diversified over time on Earth, giving rise to the different strains of bacteria we observe today.

Further Explanation:
- The argument focuses on the differences in protein structure between strains of bacteria from different planets.
- It assumes that these differences would persist over time and prevent the survival of Venusian bacteria on Earth.
- However, this assumption overlooks the possibility of evolution and adaptation of the transported bacteria on Earth.
- Bacteria are known to undergo genetic mutations and evolve over time.
- It is possible that the Venusian bacteria, if they did arrive on Earth, could have adapted to their new environment and diversified into different strains.
- These strains may have undergone further genetic changes and natural selection processes, leading to the bacterial diversity observed on Earth today.

Conclusion:
The argument in the passage is most vulnerable to the criticism that it fails to consider whether all bacteria now on Earth could have arisen from transported Venusian bacteria. This criticism highlights the possibility of the transported bacteria evolving and adapting to Earth's environment, leading to the diversity of bacterial strains observed today.
