Input: Consider Input: Article: This is a true story that happened in Japan. In order to _ the house, a Japanese tore open the walls. Japanese houses normally have a empty space between the wooden walls. When tearing down the walls, he found that there was a lizard stuck there because a nail from outside was hammered into one of its feet. He saw this, feeling pity and curious. When he checked the nail, he found it was nailed 10 years ago when the house was first built. What happened? The lizard had survived in such a position for 10 years! It has been in a dark wall partition for 10 years without moving! Then he wondered how this lizard survived for 10 years without moving a single step--since its foot was nailed! So he stopped his work and observed the lizard: What has it been doing? What and how has it been eating? Later, he didn't know from where another lizard appeared, with food in its mouth. Ah! He was astonished and touched deeply. The free lizard had been feeding the stuck one for the past 10 years. Such love, a beautiful love! Such love happened with this tiny creature... What can love do? It can do wonders! Just think about it: one lizard had been feeding the other one untiringly for 10 long years, without giving up hope on its partner. If a small creature like a lizard can love like this, just imagine how we can love if we try.
Question: How did the Japanese feel when seeing the stuck lizard?
Options: (A) Frightened (B) Enjoyable (C) Confused (D) Usual

Output: C

Input: Consider Input: Article: Last year, around Labor Day, I read a "Happy Ad" in our local newspaper. There was a lady in a local nursing home, who was celebrating her 90th birthday and her family wanted everyone to know about it. It said that if you wanted to drop her a line, here was her address. So I did. I found a birthday card and dropped her a short note, wishing her a happy birthday. A week or so later, someone knocked at my front door. I opened the door and found a middle-aged man standing on my doorstep. He introduced himself as the son of this woman to whom I had sent the card. He explained that he just wanted to drop by in person and thank me for sending such a nice card to his mom. Apparently, like many older folks, she did not receive much mail and was quite excited to receive mine. I just didn't know what to say. I told him it was my pleasure and that I hoped his mom had enjoyed her birthday. That year, I did not send out any Christmas cards, except to this lovely old lady in the nursing home. I just told her that I was thinking about her and hoped that she had a nice holiday. I sent her a Valentine and also a couple of notes in between. I just thought she might like to have someone write to her, to get some mail. She passed away a couple of months ago. I never met this lady, but I did keep her and her family in my thoughts. I dropped them a line of sympathy. I hope that my few little notes were enough to brighten a couple of her days here on earth.
