Step-by-step explanation:
To answer these questions, we need to remember the standard word order in English:
Subject + Verb + Object.
We also need to remember that, even though most adverbs can be placed in different parts of a sentence without changing its meaning, they are usually placed near the verb that they modify, and there are some rules to place them correctly.
For example, adverbs of degree are usually placed before the adjective, adverb, or verb that they modify. So in the first question, the correct order is: "totally forgot."
Adverbs of time are usually placed at the beginning or at the end of a sentence. So in the second question, "twice a year" should be located at the end.
