Explanation:
The Future perfect tense is primarily employed to denote an action that will have been accomplished or completed before a specific time in the future. Such action is expected to be perfected before that time. The sentence in the future perfect tense is framed using 'subject + 'will have' + past participle form of the verb.' The use of 'will' denotes future and 'have' helps in expressing the perfection of the action. Thus, as per this rule, the above sentences are framed by conjugating the verb 'to know' with the given subjects.
Getting your high school diploma is very important for several reasons. First of all, it is relevant career-wise: without a diploma, there aren't many jobs that you can apply for and actually get. Nowadays, employers don't only look at the skills you have to perform a particular job, but also whether or not you own a particular diploma. If you don't, chances are you won't get that desired job as many better jobs now require you to have specific knowledges which can only be attained if you have a diploma. Other than that, there is a stigma nowadays that if you are a high school dropout and don't have a diploma to prove your knowledge, you might be considered of lesser value than those who own a diploma. So it is easier to actually finish high school and get a diploma than to be an outcast in a society which values achievements more than anything else.
