Example Input: Article: Give people a chance before you judge them because you really never know what's going on beneath the surface. I am always reminded that judging a person by what others say or my first impression is usually wrong. It's so easy to make assumptions and expectations about someone, just to find out they were completely false. The shy girl turns out to be one of the funniest girls I've ever met; the mean girl is actually very sensitive and loving; the _ guy is unsure of himself, etc. I hope there is a world where we stop judging a person by what they wear, their hairstyle, their job, their car; we simply love and accept them for who they are. Someone may have untidy hair because they over slept, or their clothes don't match because their house burned down and lost everything. All I'm saying is, "can we focus more on what's going on inside a person rather than the outside?" There are so many people who seem like everything is just fine on the outside, but the inside is angry or hurting. They don't know how to just be themselves or they're afraid to because they may be seen as the "crazy" or "strange" persons. I truly believe everything begins with ourselves. Before we can really stop judging others by the outside, we must stop judging ourselves. We must know how to treat ourselves first. Let's stop getting in our own way and accept ourselves and others as we are.
Answer: what's going on inside him
Example Output: When we judge a person, we should pay more attention to _ .

Example Input: Article: If you walk around any large city, you'll find a coffee shop on every corner. Many shops offer comfortable sofas, large screen televisions and sometimes even live music. More and more teenagers are hanging out there. My pre-teen has already done so after school once a month, but she always orders fruit juice. I think she would drink coffee sooner or later, so I started doing some research online. I found that coffee in moderation could be safe, but one thing that was constant online was the chance of becoming addicted to coffee. Coffee is one step up from soda but still not as dangerous as energy drinks or alcohol. Still, any addiction is hard to break, so I needed to come up with a plan that would protect my child. Coffee shops offer a safe place for teenagers to hang out. As like anything else you let your children do, you need to set limits. Drinking coffee while socializing once or twice a week won't cause a severe caffeine addiction. However, you should avoid allowing a cup of coffee every morning and ensure they get adequate sleep each night, which will make them less likely to feel the need to drink coffee. As parents, we have responsibility to set a good example. If you're addicted to caffeine, it's time to start monitoring your intake. If you drink much water and keep healthier drink options in your fridge and at your dinner table, your teenager will follow you. I drink much water and so do both my children. _ As a mother, I'm ready to allow my child to try coffee and we'll talk about it and discuss the pros and cons of consuming this. I feel open communication is vital in helping them make good decisions. Although the decision to drink coffee doesn't pose the same dangers as underage drinking, it still deserves a thoughtful conversation.
