Explanation:

Here’s the thing—let’s take this step by step.

- The original equation is: 7 + 56 ÷ 8 ÷ 2 - 13 = 11

- Let’s solve it as-is first.

56 ÷ 8 = 7; then 7 ÷ 2 = 3.5

So: 7 + 3.5 - 13 = -2.5 (Nowhere near 11.)

Let’s try swapping pairs, option by option:

- Option 1: Swap 7 and 8

- New equation: 8 + 56 ÷ 7 ÷ 2 - 13 = 11

56 ÷ 7 = 8; 8 ÷ 2 = 4

8 + 4 - 13 = -1

Still, not 11.

- Option 2: Swap 7 and 13

- Equation: 13 + 56 ÷ 8 ÷ 2 - 7

56 ÷ 8 = 7; 7 ÷ 2 = 3.5

13 + 3.5 - 7 = 9.5

Closer, but not 11.

- Option 3: Swap 7 and 2

- Equation: 2 + 56 ÷ 8 ÷ 7 - 13

56 ÷ 8 = 7; 7 ÷ 7 = 1

2 + 1 - 13 = -10

Still off.

- Option 4: Swap 8 and 2

- Equation: 7 + 56 ÷ 2 ÷ 8 - 13

56 ÷ 2 = 28; 28 ÷ 8 = 3.5

7 + 3.5 - 13 = -2.5

Not 11.

Let me tell you plainly:

- None of these swaps give you exactly 11, but Option 2 comes closest (9.5). The other swaps land further from 11.

So, the most reasonable answer among the given options is Option 2: 7 and 13.

Option 2 is the right pick here.
