Given below is a statement followed by two conclusion numbered I and II. You have to assume everything in the statement to be true, even if it appears at variance from commonly known facts. Then consider the two conclusions together and decide which of them information given in the statement. Statement: A research found that if high school students get eight hours of sleep instead of 6 hours before exam, then their marks improve by 20% Conclusions: I. Eight hours of sleep is better than six hours of sleep if a student wants better marks. II. Student are stressed as all exams are tough.
Only conclusion I follows
Analyzing the Statement and Conclusions
The question provides a statement followed by two conclusions. We need to evaluate which of these conclusions logically follow from the information given in the statement, assuming the statement is entirely true.
Understanding the Statement
The statement presents a research finding related to high school students, sleep, and exam performance:
- Statement: A research found that if high school students get eight hours of sleep instead of 6 hours before exam, then their marks improve by 20%.
This statement establishes a cause-and-effect relationship, or at least a strong correlation, specifically for high school students before an exam. Getting 8 hours of sleep is associated with better marks (a 20% improvement) compared to getting only 6 hours of sleep.
Evaluating Conclusion I
- Conclusion I: Eight hours of sleep is better than six hours of sleep if a student wants better marks.
Let's compare this conclusion with the statement:
- The statement says 8 hours of sleep instead of 6 hours improves marks by 20%.
- Conclusion I says 8 hours is better than 6 hours if a student wants better marks.
The statement explicitly provides evidence that getting 8 hours of sleep results in better marks (specifically, a 20% improvement) compared to 6 hours. Therefore, based on the statement, for a student aiming for better marks, 8 hours of sleep is indeed shown to be better than 6 hours. Conclusion I is a direct and logical inference from the information provided in the statement.
Evaluating Conclusion II
- Conclusion II: Student are stressed as all exams are tough.
Now, let's compare this conclusion with the statement:
- The statement talks about the effect of sleep duration (8 vs 6 hours) on exam marks.
- The statement does not mention anything about students' stress levels.
- The statement does not mention whether exams are tough or not.
Conclusion II introduces information (student stress, toughness of exams) that is completely outside the scope of the given statement. The statement provides no basis or evidence to support the claims made in Conclusion II. Therefore, Conclusion II does not follow from the statement.
Determining Which Conclusions Follow
Based on the analysis:
- Conclusion I logically follows from the statement.
- Conclusion II does not follow from the statement.
Thus, only Conclusion I follows.
Choosing the Correct Option
The option that states only Conclusion I follows is the correct one.
Let's look at the given options:
- Only conclusion II follows: Incorrect, as Conclusion II does not follow.
- Neither conclusion I nor II follows: Incorrect, as Conclusion I follows.
- Only conclusion I follows: Correct, as only Conclusion I is a valid inference.
- Both conclusions I and II follow: Incorrect, as Conclusion II does not follow.
| Conclusion | Does it Follow? | Reasoning |
|---|---|---|
| I. Eight hours of sleep is better than six hours of sleep if a student wants better marks. | Yes | Directly supported by the statement which shows 8 hours leads to 20% improvement over 6 hours. |
| II. Student are stressed as all exams are tough. | No | The statement provides no information about student stress or exam difficulty. |
Revision Table: Statement and Conclusion Analysis
| Concept | Key Point | Application Here |
|---|---|---|
| Statement & Conclusion | Assess logical relationship between statement (assumed true) and conclusions. | Checking if conclusions are necessary inferences from the given statement only. |
| Following from Statement | Conclusion must be solely based on the information in the statement. | Conclusion I directly reflects the sleep-marks relationship shown. Conclusion II introduces external ideas. |
| Scope of Statement | Only use facts given in the statement, even if they contradict common knowledge. | Focus only on the finding about sleep hours and marks improvement for high school students before exams. |
Additional Information: Drawing Inferences
In statement and conclusion type questions, the key is to strictly adhere to the information given in the statement. You should not use your prior knowledge, beliefs, or general facts to evaluate the conclusions. A conclusion 'follows' if it is necessarily true based *only* on the statement provided.
- A valid conclusion is an inference that can be drawn directly and logically from the statement.
- If a conclusion introduces new information or makes assumptions not present in the statement, it does not follow.
- Even if a conclusion seems factually correct in the real world, it only follows in the context of the question if the statement supports it.
In this specific problem, the statement provides a clear link between more sleep (8 vs 6 hours) and better marks. Conclusion I simply restates this finding in terms of one being 'better' than the other for a specific goal (better marks), which is a valid inference. Conclusion II, about stress and tough exams, is entirely unsupported by the statement and therefore does not follow.
