< b="" />Can vs Could: My Brother's Motorcycle and Car Skills< />
Can vs Could Explanation:

Can:
- If you say "My brother can write a motorcycle as well as drive a car," you are indicating that he has the ability to do both tasks in the present.
- This implies that he currently possesses the skill to ride a motorcycle and drive a car.

Could:
- If you say "My brother could write a motorcycle as well as drive a car," you are referring to his ability in the past or to a hypothetical situation.
- This suggests that at some point in the past, he had the ability to do both tasks, or that he hypothetically has the ability to do so.
In this context, if you are referring to your brother's current abilities, the correct choice would be "can." However, if you are talking about his past abilities or a hypothetical scenario, you could use "could." Ultimately, the choice between "can" and "could" depends on the timeframe or context in which you are discussing your brother's skills.
