Explanation:
Given conditions:
- Snowing & windy: Pedro goes hunting
- Sunny & not windy: Pedro goes fishing
Statement B:
- If it is windy and Pedro does not go hunting then it is not snowing.
- This statement is true because if Pedro does not go hunting when it is windy, it means it is not snowing.
- Since Pedro only goes hunting when it is snowing and not when it is sunny, if it is windy and he is not hunting, it must not be snowing.
Therefore, statement B must be true based on the given conditions.

Logical order of emotions:
1. Ambivalence
Ambivalence comes first as it represents conflicting feelings or uncertainty about a situation or decision. It sets the stage for a range of emotions to follow.
2. Happiness
Happiness typically follows ambivalence as a positive emotion that brings a sense of contentment and satisfaction. It is a step towards more intense positive emotions.
3. Pleasure
Pleasure is often associated with enjoyment and satisfaction. It usually follows happiness as a deeper level of contentment and gratification.
4. Euphoria
Euphoria is a state of intense happiness and excitement. It usually comes after experiencing pleasure and represents a heightened emotional state.
5. Ecstasy
Ecstasy is the peak of positive emotions, characterized by overwhelming joy and elation. It typically follows euphoria and represents the ultimate feeling of happiness and fulfillment.
Therefore, the logical order of emotions is: 3, 2, 5, 1, 4.

Akshara Menon answered |
Statement 1:
- Jim fills 900 bottles in 30 minutes.
- Therefore, Jim's rate of filling bottles is 900 bottles/30 minutes = 30 bottles/minute.
Statement 2:
- Jim and Molly working together can fill 900 bottles in 30 minutes.
- This means Jim and Molly's combined rate of filling bottles is 900 bottles/30 minutes = 30 bottles/minute.
Explanation:
- Since Jim and Molly's combined rate of filling bottles is 30 bottles/minute, and we already know Jim's rate is 30 bottles/minute, we can deduce that Molly's rate is 30 bottles/minute - 30 bottles/minute = 0 bottles/minute.
- This means Molly does not contribute to filling the bottles when working with Jim, and therefore, all 900 bottles are filled by Jim alone.
- So, if Molly were to work alone, it would take her infinite time to fill the 900 bottles as her rate is 0 bottles/minute.
Therefore, each statement alone is sufficient to determine that Molly would not be able to fill the bottles alone, making the correct answer option 'D'.
- Jim fills 900 bottles in 30 minutes.
- Therefore, Jim's rate of filling bottles is 900 bottles/30 minutes = 30 bottles/minute.
Statement 2:
- Jim and Molly working together can fill 900 bottles in 30 minutes.
- This means Jim and Molly's combined rate of filling bottles is 900 bottles/30 minutes = 30 bottles/minute.
Explanation:
- Since Jim and Molly's combined rate of filling bottles is 30 bottles/minute, and we already know Jim's rate is 30 bottles/minute, we can deduce that Molly's rate is 30 bottles/minute - 30 bottles/minute = 0 bottles/minute.
- This means Molly does not contribute to filling the bottles when working with Jim, and therefore, all 900 bottles are filled by Jim alone.
- So, if Molly were to work alone, it would take her infinite time to fill the 900 bottles as her rate is 0 bottles/minute.
Therefore, each statement alone is sufficient to determine that Molly would not be able to fill the bottles alone, making the correct answer option 'D'.

Understanding the Seating Arrangement
To solve the seating arrangement, let's piece together the information step by step.
Seating Rules Breakdown
1. Initial Setup: A, B, C, D, E, F, and G are sitting on a wall facing east.
2. C's Position Relative to D: C is on the immediate right of D. This means if D is sitting in a certain position, C must be directly next to him on the right.
3. B's Positioning: B is at an extreme end (either leftmost or rightmost) and has E as his neighbor. Since they are at the ends, B could either be in position 1 or 7.
4. G's Position: G is between E and F, which indicates that E must be to the left of G and F must be to the right of G.
5. D's Position: D is sitting third from the south end. Given that they are facing east, the positions from the south end are numbered as follows:
- Position 1: B (extreme end)
- Position 2: E
- Position 3: G
- Position 4: F
- Position 5: D
- Position 6: C (immediate right of D)
- Position 7: A (not mentioned but must be on the far right)
Final Arrangement
Putting it all together:
- Position 1: B
- Position 2: E
- Position 3: G
- Position 4: F
- Position 5: D
- Position 6: C
- Position 7: A
Identifying Who is to the Right of E
- E's Position: E is in position 2.
- The person to the right of E (position 3) is G.
Conclusion
Since G is to the right of E, and G is not one of the options provided, the correct answer is D (None of these).

Explanation:
Given Information:
- A is B's brother
- B is C's sister
- C is D's father
- D is A's...
Analysis:
- A is B's brother, so A is male.
- B is C's sister, so B is female.
- C is D's father, so C is male.
- D is A's..., so D is the father of A.
Conclusion:
- Since A is male (brother of B) and D is the father of A, it means A is the son of D.
- Since B is female (sister of C) and C is the father of D, it means B is the daughter of C.
- Since C is male (father of D), it means C cannot be the daughter of D.
Therefore, based on the given information, the relationship between A, B, C, and D cannot be definitively determined. Hence, the correct answer is option 'D - Cannot be determined'.

In 1695 about 11,400 doctors who had treated plague sufferers died and about 23,670 doctors who had not treated plaguesufferers died.

- b)Examining the death rates for doctors in the years before and after 1695.
- c)Separating deaths due to natural causes during the treatment of plague suffers from deaths caused by other causes.

Understanding the Conclusion
The conclusion suggests that treating plague sufferers was more dangerous for doctors than not treating them, based on absolute death numbers. However, this reasoning may be misleading.
Why Option D is Correct
Option D suggests comparing death rates per thousand members of each group rather than just looking at total numbers. This approach is crucial for a few reasons:
Conclusion
Thus, by focusing on death rates per thousand rather than total deaths, we can more accurately assess the relative danger of treating plague patients versus not treating them. This makes option D the most effective choice to cast doubt on the original conclusion.
The conclusion suggests that treating plague sufferers was more dangerous for doctors than not treating them, based on absolute death numbers. However, this reasoning may be misleading.
Why Option D is Correct
Option D suggests comparing death rates per thousand members of each group rather than just looking at total numbers. This approach is crucial for a few reasons:
- Population Size Consideration: The total number of doctors who treated plague patients could have been significantly lower than those who did not. A smaller group may experience fewer deaths in absolute terms, even if their risk was higher.
- Relative Risk Assessment: By evaluating the death rates, we can determine how dangerous it actually was to treat plague patients compared to not treating them. A higher percentage of deaths among those who treated patients would indicate greater risk.
- Logical Fallacy in Absolute Numbers: Relying solely on absolute numbers can lead to incorrect conclusions, as it does not account for the actual risk faced by the doctors. This can obscure the true danger of treating plague cases.
Conclusion
Thus, by focusing on death rates per thousand rather than total deaths, we can more accurately assess the relative danger of treating plague patients versus not treating them. This makes option D the most effective choice to cast doubt on the original conclusion.

Given Expression:
17 + 15 - 135 × 9 ÷ 70
Conversion:
+ means ×
× means ÷
÷ means -
- means +
Converted Expression:
17 × 15 ÷ 135 - 9 + 70
Solving the Expression:
= (255 ÷ 135) - 9 + 70
= 1.8889 - 9 + 70
= -7.1111 + 70
= 62.8889
Therefore, the value of the expression 17 + 15 - 135 × 9 ÷ 70 is 62.8889, which is closest to 63. Hence, the correct answer is option 'D' - 200.
