    To find which of these options is a rational number between \( \sqrt{7} \) and \( \sqrt{8} \), we first need to approximate the square roots.
Calculating \( \sqrt{7} \) and \( \sqrt{8} \):
- \( \sqrt{7} \approx 2.64575 \)
- \( \sqrt{8} = 2\sqrt{2} \approx 2.82843 \)
Now, we can check which of the given rational numbers lies between \( \sqrt{7} \) and \( \sqrt{8} \).
1. **Check \( \frac{5}{6} \):**
\[
\frac{5}{6} \approx 0.8333 \quad (\text{not between } 2.64575 \text{ and } 2.82843)
\]
2. **Check \( \frac{19}{7} \):**
\[
\frac{19}{7} \approx 2.7143 \quad (\text{between } 2.64575 \text{ and } 2.82843)
\]
3. **Check \( \frac{3}{4} \):**
\[
\frac{3}{4} = 0.75 \quad (\text{not between } 2.64575 \text{ and } 2.82843)
\]
4. **Check \( \frac{6}{3} \):**
\[
\frac{6}{3} = 2 \quad (\text{not between } 2.64575 \text{ and } 2.82843)
\]
Out of all the options, \( \frac{19}{7} \) is the only rational number that lies between \( \sqrt{7} \) and \( \sqrt{8} \).
Therefore, the answer is \( \frac{19}{7} \).

    Let's double-check the calculations step-by-step to confirm whether \( \frac{19}{7} \) really lies between \( \sqrt{7} \) and \( \sqrt{8} \).
1. **Confirm values of \( \sqrt{7} \) and \( \sqrt{8} \)**:
- \( \sqrt{7} \approx 2.64575 \)
- \( \sqrt{8} = 2\sqrt{2} \approx 2.82843 \)
2. **Calculate \( \frac{19}{7} \)**:
\[
\frac{19}{7} \approx 2.714285714285714 \quad (\text{which is roughly } 2.7143)
\]
Now, comparing \( \frac{19}{7} \) to \( \sqrt{7} \) and \( \sqrt{8} \):
- Since \( 2.64575 < 2.7143 < 2.82843 \), we can conclude that \( \frac{19}{7} \) is indeed between \( \sqrt{7} \) and \( \sqrt{8} \).
Thus, my previous answer stands verified; \( \frac{19}{7} \) is a rational number that lies between \( \sqrt{7} \) and \( \sqrt{8} \). If you have any further questions or need clarification, feel free to ask!
