How do you make Either can eat or talk but both at the same time into parallel structure?

The phrase "Either can eat or talk but both at the same time" is not grammatically correct and lacks parallel structure. Here are a few ways to rewrite it with parallel structure:

Option 1: Using "and"

* "One can either eat or talk, but not both at the same time." This clarifies that the actions are mutually exclusive.

Option 2: Using "or"

* "One can either eat or talk, but not simultaneously." This emphasizes the inability to do both actions at once.

Option 3: Using a more descriptive phrase

* "One can either consume food or communicate verbally, but not engage in both activities concurrently." This option is more formal and verbose.

Option 4: Using a negative construction

* "One cannot eat and talk at the same time." This directly states the limitation.

The best option for you will depend on the context and the desired tone.
