Answer:
The question asks for an example of a scientific question that could be used to start a scientific investigation. A scientific question is one that can be tested through measurable observations and experimentation. It should be specific, focused, and answerable through empirical research.
Looking at the options:
A. Which dog breeds make the best pets for small children?
This question is subjective and depends on personal preferences, the child's behavior, and the specific dog's temperament. It cannot be universally answered through scientific investigation.
B. What kinds of things do dogs dream about?
This question is not currently answerable by science as we do not have a definitive way to measure or observe what dogs (or any other animals) dream about.
C. Should some dog breeds be banned by community authorities?
This is a policy or ethical question, not a scientific one. It involves value judgments and societal norms, which are outside the realm of empirical science.
D. Does the brand of food eaten by a dog affect the amount of fur it sheds?
This is a scientific question. It can be tested through controlled experiments where different groups of dogs are fed different brands of food and their fur shedding is measured over time.
Therefore, the correct answer is D: "Does the brand of food eaten by a dog affect the amount of fur it sheds?" This question can be empirically tested using controlled experiments and statistical analysis to determine if there is a significant difference in fur shedding between dogs fed different brands of food.
