In the following introductory paragraphs, what kind of motivator does the author apply? _______1) “No union is more profound than marriage, for it embodies the highest ideals of love, fidelity, devotion, sacrifice and family,” Justice Anthony Kennedy rightly argued in his majority opinion in the Obergefell v. Hodges case. Even today, when marriage is less likely to guide our lives, relationships and families, it’s still the case that marriage is without peer when it comes to calling forth the best in our relational lives. ______ 2) Some children grow up wanting to play baseball all day, but I wanted to play Castlevania and Super Mario Brothers. Sadly, my parents believed I’d fry my brain for the love of videogames, so I was limited to an hour of screen time before dinner. _______ 3) Even though multiple generations have now grown up glued to the flickering light of the TV, we still can’t let go of the belief that the next generation of technology is going to doom our kids. We blame technology, rather than work, to understand why children engage with screens in the first place. _______4) I stare disapprovingly at the crumpled twenty that’s been pushed across the table toward me. Obviously, the money is old; acquired many years ago. My gaze shifts up to the expectant face that lies a few meters away from me. An eyebrow rises on my forehead, and I make no move to grab the green cash. _______5) Should a person who is not terminally ill be allowed to commit suicide? If so, should physicians be permitted to assist in causing the person’s death? Should non-physicians?

Underline the thesis statement in the following two paragraphs. 1) If you spend some time, as I have, interviewing professional matchmakers, you'll learn there is no shortage of college-educated women seeking to get married. The only shortage is among men. 2) The harms that can come to children who use technology excessively — including depression, behavioral problems and poor academic performance — are not just caused by too much screen time. It is the nature of the interactions that take place through the screen that count. Simply limiting screen time ignores the many benefits of technology for teenagers.
