Context: Then , a month of being home alone made me realise I did n't cook any meat , nor did I have any desire to cook or eat meat , so why should I ? Just to fuel the veggie - thoughts further , I started looking on the net at slaughterhouses , videos of what the do to pigs and the conditions they live in . There 's videos of them being picked up by their hind legs and slammed into the concrete floor because they 're too weak , and falling out of trucks too weak to stand up when they arrive at the slaughterhouses .

Question: What may be the reason why they watched such horrible videos ?
Options:
0. None of the above choices .
1. To ensure that they do n't eat meat .
2. To find out how to make their own bacon .
3. To get information on how to run a slaughterhouse .
Answer: 1
