A packet or rice that had already been cooked earlier.
Explanation:
The question is asking us to take our knowledge of prefixes and suffixes into consideration. It wants us to explain the meaning of the word that contains either a prefix or a suffix. We are told we purchased a packet of precooked rice. It is easy to recognize the prefix attached to the word "cooked".
The prefix pre- means in advance, early, before, beforehand. The very word "prefix" has it, meaning there is an affix that is placed before the word. Thus, when we say something is precooked, we mean that it has been cooked before. Precooked meals are faster to prepare since most of them have been cooked and then dehydrated. All you have to do is add hot water to it and it's ready.
