Text: Why, they ask, does the fact that a fetus can survive outside the womb with the help of vast medical technology change either of the interests at war in the abortion  the fetus's own claim to human-ness and a woman's right to control her body?
Entailment: The viability of the fetus outside of the room doesn't change the fundamental rights being argued for.
Contradiction: The ability of the fetus to survive with the assistance of technology completely changes the nature of the argument concerning the divergent interests of the woman and the fetus.
