Let's analyze the question from the image:

**Question:**  
"Which sum or difference could have an estimate of 2? Select all that apply."

We need to determine which of the given sums or differences approximate to 2. Let's go over each option:

---

### **Option A: \( 1 \frac{8}{10} + \frac{1}{8} \)**
- \( 1 \frac{8}{10} \approx 1.8 \)  
- \( \frac{1}{8} \approx 0.125 \)  
- Sum: \( 1.8 + 0.125 \approx 1.925 \) (close to 2)  
**This is a possible answer.**

---

### **Option B: \( 2 \frac{1}{10} - \frac{6}{10} \)**
- \( 2 \frac{1}{10} \approx 2.1 \)  
- \( \frac{6}{10} = 0.6 \)  
- Difference: \( 2.1 - 0.6 = 1.5 \) (not close to 2)  
**Not a valid option.**

---

### **Option C: \( 1 \frac{7}{16} + 1 \frac{7}{8} \)**
- \( 1 \frac{7}{16} \approx 1.4 \)  
- \( 1 \frac{7}{8} \approx 1.875 \)  
- Sum: \( 1.4 + 1.875 \approx 3.275 \) (far from 2)  
**Not a valid option.**

---

### **Option D: \( 2 \frac{1}{3} - 1 \frac{3}{14} \)**
- \( 2 \frac{1}{3} \approx 2.33 \)  
- \( 1 \frac{3}{14} \approx 1.21 \)  
- Difference: \( 2.33 - 1.21 \approx 1.12 \) (not close to 2)  
**Not a valid option.**

---

### **Option E: \( 1 \frac{5}{14} + 1 \frac{1}{4} \)**
- \( 1 \frac{5}{14} \approx 1.36 \)  
- \( 1 \frac{1}{4} = 1.25 \)  
- Sum: \( 1.36 + 1.25 = 2.61 \) (close to 2, but a bit high)  
**This could be considered close to 2.**

---

### **Conclusion:**
- **Correct options:** A and E
