To determine the correct completion for the sentence "They would not let me ________ to watch the film," we first need to analyze the options provided:

1. staying up
2. to stay up
3. stay up
4. None of the given options

Analysis of Options

1. staying up: This option uses the gerund form. In this context, it doesn’t fit because "let" typically requires a base verb form.

2. to stay up: This is the infinitive form. However, when you use "let," the structure typically does not require "to."

3. stay up: This is the base form of the verb, which is the correct form to use after "let."

4. None of the given options: This would be valid if none of the other options fit correctly.

Conclusion

The most appropriate completion of the sentence is "stay up." Therefore, the full sentence would read: "They would not let me stay up to watch the film."
