A woman is considered to be in labor when she begins experiencing regular uterine contractions, accompanied by changes of her cervix – primarily effacement and dilation. While childbirth is widely experienced as painful, some women do report painless labors, while others find that concentrating on the birth helps to quicken labor and lessen the sensations. Most births are successful vaginal births, but sometimes complications arise and a woman may undergo a cesarean section. What inferences can be drawn from the above paragraph? Correct Answer Painless labor is a rarity. Option 1 is wrong, as pregnancy does involve uterine pain, however, uterine pain could also be an indication of another disease, and does not always involve a pregnancy. Option 2 is correct, as it is mentioned that 'childbirth is widely experienced as painful', and that 'some women' experience painless labor. Option 3 is also wrong, as nowhere in the paragraph is it mentioned that a successful birth is only a vaginal birth. It is a wrong inference. Hence, only option 2 is correct.
