Context: I have n't read up on the process or the pros and cons about it , but I do know ppl who have gone through it unscathed and my Dr. has assured me that there is nothing wrong with having a baby by that method . I think it would be better because everytime the two of us are measured , they keep telling me how big he is . Granted , I have n't gained a lot of weight so far with this pregnancy . Only thirteen pounds so far , which I think is fabulous . Most horror stories I hear are of women gaining roughly fifty pounds .

Question: Why might I only have gained 13 pounds during this pregnancy ?
Options:
0. Because I might have exercised and watched what I ate during this pregnancy .
1. Because I might have exercised but did n't watch what I ate during this pregnancy .
2. Because I might have exercised and watched what I ate during the last pregnancy .
3. Because I might have been lazy and did n't watch what I ate during this pregnancy .
Answer: 0
