To convert the high-level language instructions to assembly language instructions, we need to follow the semantic operations indicated in each statement. Here's the continuation for each of the points you've provided:
1) For the instruction `Input`, you want to load the value into memory location associated with `z`, which is `M[7]`. Assuming there is a command to read input, it would typically look like this:
```assembly
Input M[7] ; Store the input value from the user into memory location M[7]
```
2) The operation `x = y + z` should add the values stored in `M[6]` (for y) and `M[7]` (for z) and store the result in `M[5]` (for x). The assembly operation for this would look like this:
```assembly
Add M[6] ; Add the value of M[6] (y) to the accumulator
Add M[7] ; Add the value of M[7] (z) to the accumulator
Store M[5] ; Store the result in M[5] (x)
```
3) For the operation `x = 2 * y`, you want to add `y` to itself and store the result in `x`. Since `y` is in `M[6]`, it would look like this:
```assembly
Add M[6] ; Add the value of M[6] (y) to the accumulator
Add M[6] ; Add the value of M[6] (y) again to the accumulator
Store M[5] ; Store the result in M[5] (x)
```
4) For the instruction `x = y + y + y`, since you mentioned the command `Add M[5] M[6] M[6]` has already been entered (which adds `y` to itself once and stores it in `x`), we should complete the remaining addition of `y`:
```assembly
Add M[6] ; Add M[6] (y) to the result (which is currently in M[5])
Store M[5] ; Store the final result back in M[5] (x)
```
This series of instructions should adequately represent the intended operations in assembly language.

Add M[6] ; Add M[6] (y) to the result (which is currently in M[5])
