Answer:
1. No, this is not always true. While working hard can absolutely help you achieve your goals, there will be, on occasion, a dream that one cannot fulfil regardless of how hard they work. For example, an aspiring doctor will not complete medical school if they simply lack the aptitude for the work.
2. This is also not always true, as it is dependent on the "others" that the question refers to. Simply put, not every person is good to be around. Some may be bad influences, toxic, or generally bad people. Others, however, are good to be around.
3. This is true. There is not always a "better way," nor a good choice for a solution. For example, a "sacrifice the few to save the many" situation has no good solution because people, even a few, will still have to be sacrificed.
4. This is a very morally grey question because it highly depends on the disability and situation. For example, a person with a limited intellectual capacity may not understand that taking things without permission is wrong. However, we should also ask: if a person with an intellectual disability murders someone in rage, not understanding the concept of death or murder, can they be held accountable to something they cannot comprehend?
