Answer 1

To specify how many cups of flour should be used in a bread recipe, the number must be a non-negative and typically a rational number. Let's evaluate the options:

1. **−3**: This is negative and cannot represent a quantity of flour. **Not valid.**

2. **square root of 3**: This is a positive number (approximately 1.732) but is not a whole number or a common fraction for a recipe. However, it can technically represent a quantity. **Valid but unconventional.**

3. **234**: This is a positive whole number and can represent the amount of flour needed. **Valid.**

4. **2 Start Fraction 3 over 4 End Fraction**: This notation seems to indicate 2.75 (or 2 and 3/4), which is also a positive quantity representing a reasonable amount of flour in a recipe. **Valid.**

5. **47**: This is also a positive whole number and can represent the amount of flour needed. **Valid.**

In summary, the valid options for specifying how many cups of flour should be used in a bread recipe are:
- square root of 3
- 234
- 2 Start Fraction 3 over 4 End Fraction
- 47
