My little brother _____ the same mistake again and  again.*always makesmadeis always makingis making

To fill in the blank in the sentence "My little brother _____ the same mistake again and again," we need to choose the correct verb form that accurately describes a recurring action.

Analysis of Options:

1. always makes: This suggests a habitual action and is grammatically correct. It implies that the brother consistently repeats the mistake.
2. made: This is in the past tense, which doesn't fit the context since the action is ongoing.
3. is always making: This is present continuous, which indicates that he is currently making the mistake frequently, but it suggests a more temporary situation.
4. is making: This form implies that he is currently in the process of making the mistake, which does not convey the ongoing habitual nature as clearly as "always makes."

Conclusion:

The best choice is "always makes," as it captures the idea of a repeated action effectively.

Final Answer:

My little brother always makes the same mistake again and again.
