Explanation:

The simple tense is characterized into three categories in order to denote facts or regular actions. Present simple expresses habitual actions(using V1 + s/es) while past simple denotes an action that took place in the past(time before now using V2) and the future simple is used to show actions that will take place in the future.

Progressive or Continuous tense talks about the continuity of an action, be it in present, be it in past, or will be in progression in the future. In present progressive, the continuity is shown using 'is/am/are + V1 + ing' while in the past progressive 'was/were + V1 + ing' and in the future progressive 'will/shall + be + V1 + ing' is used.

The perfect tense is employed to express the actions that have been completed or will have been completed at a specific time in the future. Thus, it is called perfect. It employs 'has/have + V3'(in present), 'had + V3'(in past), and 'will/shall + have + V3'(in future).

While the perfect continuous/progressive tense is to display an action that began at a specific time and is in continuity, was in continuity, or will be in continuity till a particular time. Thus, it shows perfection and continuity at the same time.

In present perfect progressive, the rule 'has been/have been + V1 + ing + since/for' while in the past perfect progressive, 'had been + V1 + ing + since/for' is employed and in future progressive tense, 'will have been/shall have been + V1 + ing + since/for' is employed.

answer: this is not a good thesis statement because a thesis statement is not supposed to have questions in it. a thesis states your position on your topic. a question cannot state anything because it is not a statement. a question is a great lead in to a thesis, but it can't be the thesis.
