Select the most appropriate word to fill in the blank and make a meaningful sentence.

The method ______ by the teacher is very tedious.

suggested

The most appropriate word to fill in the blank is suggested.

The sentence is saying that the method suggested by the teacher is very tedious. The word "suggested" indicates that the teacher proposed or recommended the method, and the word "tedious" means that the method is long, dull, and tiresome.

The other options are not as appropriate. The word "regarded" means to consider or think about something in a particular way. This does not make sense in the context of the sentence, as the teacher is not considering the method in a particular way, they are simply suggesting it. The word "reminded" means to bring something to someone's attention. This does not make sense in the context of the sentence, as the teacher is not reminding the students of something, they are suggesting a new method. The word "allowed" means to give permission for something to happen. This does not make sense in the context of the sentence, as the teacher is not giving permission for the method to be used, they are simply suggesting it.
