<u><em>I was asked to keep a record of all the attendees of the seminar by the organizing committee.</em></u>
Explanation:
Phrases are words, short groups of words that are used to refer to something else. They cannot be taken in the literal sense and maybe a means to refer to something else.
The phrase <em>"keep a record"</em> means to keep certain information safe.
So, making a sentence using the phrase <em>"keep a record"</em> is-
<u><em>I was asked to keep a record of all the attendees of the seminar by the organizing committee.</em></u>
so all you have to do for the first one is write about someone that happened to you in the past or if you are speaking 3rd person/2nd/person/1st person write about it like that. and for the second one just write tiny affirmations or whatever
