The correct hierarchy of number sets within the real number system, from largest to smallest, is:

**Rational numbers, integers, whole numbers, natural numbers.**

So the accurate response from your list is:

**rational numbers, integers, whole numbers, natural numbers**.

The set of numbers that are real numbers but cannot be expressed as one integer divided by another are called **irrational numbers**.

So the correct response is:

**irrational**.

Zero belongs to the following sets of real numbers:

- Whole numbers
- Integers
- Rational numbers

It does not belong to the set of natural numbers, as natural numbers typically start from 1.

So the correct response is:

**whole numbers, integers, and rational numbers**.

In a cube, all edges are equal, and if the edge length \(a\) is a rational number, the following calculations can be made:

- **Volume** of the cube is given by \(V = a^3\), which will also be a rational number.
- **Area of one of the cube’s faces** is given by \(A = a^2\), which will also be a rational number.
- **Surface area of the cube** is given by \(SA = 6a^2\), which is also a rational number.

However, the **diagonal of one of the cube’s faces** can be calculated using the Pythagorean theorem:

\[
d = \sqrt{a^2 + a^2} = \sqrt{2a^2} = a\sqrt{2}.
\]

Since \(\sqrt{2}\) is an irrational number, the diagonal measurement will require the use of irrational numbers.

So the correct response is:

**the diagonal of one of the cube’s faces**.

In a recipe, the amount of an ingredient like flour cannot be negative, and it should generally be a positive rational number represented in a meaningful way (for instance, whole cups or fractions of a cup).

Let's evaluate the options:

1. **−3**: Negative number, not valid for cups of flour.
2. **234**: Positive whole number, valid.
3. **47**: Positive whole number, valid.
4. **\( \frac{4}{7} \)**: Positive fraction, valid.
5. **Square root of 3**: While it is a positive number, it is irrational and not practical for measuring cups in a recipe.

Based on this analysis, the numbers that could be used to specify how many cups of flour should be used in a bread recipe are:

**234, 47, and \( \frac{4}{7} \)**.

Since you can only choose one option, the best choice is **234**, as it is a definite number of cups that can be used.
