The function fails when handling `'const_add'` or `'const_mul'` operations because it only recursively processes the first argument (`config[1]`), ignoring any additional arguments. These operations might have multiple arguments, but the code doesn't iterate through all of them, resulting in an incomplete history. **Exact reason:** The code for `'const_add'` and `'const_mul'` uses `make_op_with_history(config[1])` but does not process other arguments beyond the first (e.g., `config[2]`, `config[3]`, etc.), leading to missing history entries.
I asked a question about why some code was incorrect. The answer is "because because the code uses append instead of extend". Does this student answer say that? Giving multiple answers is okay as long as it also says somewhere that the code should replace the append with extend.

Answer either 'The student passes' or 'The student fails'.
The student fails.
