Final answer:
The argument exhibits the fallacy of begging the question, assuming that abortion is permissible under the law in Canada without providing evidence or justification. The legality of abortion is a complex issue determined by various factors.
Step-by-step explanation:
The argument exhibits the fallacy of begging the question. Begging the question occurs when the conclusion of an argument is assumed in one of the premises, and the premises are used to support the conclusion. In this case, the argument assumes that abortion is permissible under the law in Canada without providing any evidence or justification for this claim. However, the statement that the law says nothing about abortion does not necessarily mean that it is legal. The legality of abortion is a complex issue that is determined by various factors, including Supreme Court decisions and state regulations.
