Statement: In a one day cricket match, the total runs made by a team were 200. Out of these 160 runs were made by spinners.

Conclusion I: 80% of the team consists of spinners.
Conclusion II: The opening batsmen were spinners.

Explanation:
Conclusion I:
- The statement does not provide any information about the percentage of spinners in the team.
- We cannot assume that the entire team consists of spinners just because they made 160 runs.
- Therefore, Conclusion I does not logically follow from the given statement.

Conclusion II:
- The statement does not provide any information about the identity of the opening batsmen.
- We cannot assume that the opening batsmen were spinners just because 160 runs were made by spinners.
- Therefore, Conclusion II does not logically follow from the given statement.

Conclusion:
- Neither Conclusion I nor Conclusion II follows logically from the given statement.
- Therefore, the correct answer is option D, neither I nor II follows.

Statement: Population increase coupled with depleting resources is going to be the scenario of many developing countries in days to come.

Conclusion I: The population of developing countries will not continue to increase in the future.
Conclusion II: It will be very difficult for the governments of developing countries to provide its people a decent quality of life.

Explanation:
To evaluate the given conclusions, let's analyze the statement provided.

Population Increase Coupled with Depleting Resources: The statement mentions that the population of developing countries is going to increase while the resources are depleting. This implies that there will be a mismatch between the growing population and the availability of resources.

Conclusion I: The population of developing countries will not continue to increase in the future.
This conclusion cannot be logically deduced from the given statement. The statement only states that population increase and depleting resources will be the scenario in developing countries. It does not specify any factors that would lead to a decrease in population. Therefore, conclusion I does not logically follow.

Conclusion II: It will be very difficult for the governments of developing countries to provide its people a decent quality of life.
This conclusion logically follows from the given statement. When the population of a country increases while the resources are depleting, it becomes challenging for the government to provide a decent quality of life to its people. The limited resources will be stretched thin, making it difficult to meet the needs and aspirations of the growing population. Therefore, conclusion II logically follows.

Conclusion:
Based on the given statement, only conclusion II logically follows. It is reasonable to conclude that the governments of developing countries will face difficulties in providing a decent quality of life to their people due to the population increase and depleting resources.

Q. The old order changed yielding place to new.
Conclusions:
I. Change is the law of nature.
II. Discard old ideas because they are old.
  • a)
    Only conclusion I follows
  • b)
    Only conclusion II follows
  • c)
    Either I or II follows
  • d)
    Neither I nor II follows
Correct answer is option 'A'. Can you explain this answer?

Statement: The old order changed yielding place to new.

Conclusion I: Change is the law of nature.

To determine whether Conclusion I logically follows from the statement, we need to examine the relationship between the statement and the conclusion. The statement mentions that the old order has changed, implying that change is an inherent part of the natural process. This suggests that change is not only a possibility but also a regular occurrence in nature. Therefore, we can conclude that change is indeed the law of nature.

Conclusion II: Discard old ideas because they are old.

To assess the logical validity of Conclusion II, we need to analyze the connection between the statement and the conclusion. The statement simply states that the old order has changed, but it does not explicitly state that old ideas should be discarded solely because they are old. The statement does not provide any information about the value or relevance of old ideas. Therefore, we cannot logically conclude that old ideas should be discarded based solely on the given statement.

Conclusion:

Based on the analysis, only Conclusion I logically follows beyond a reasonable doubt from the information given in the statement. Therefore, the correct answer is option 'A' - Only conclusion I follows.
