Read the argument below and determine the underlying principle that was used to come to the conclusion presented:

Getting into the habit stretching every morning is difficult, but after $31$ days, a habit is formed. I have been stretching for about $16$ days, so in a little more than two weeks, my stretching should become a habit.

Which other argument has the same structure or pattern of argument as used above?

Option $1$: Making time to read for pleasure is difficult, but if you schedule it$,$ you$$re more likely to do it$.$ I blocked off three hours this week to read, so I should have time to enjoy a book.

Option $2$: Anyone who reads an hour a day has a decent vocabulary. Person $1$ reads three hours a day. Therefore, Person $1$ has a great vocabulary.

Option $3$: An individual is improving their test scores. Either the individual is attending all of the classes or has been keeping up with reading assignments. I know for a fact that the individual missed two weeks of classes, so they must have kept up with the work.
