If the women are single, then perhaps they would have time to wait late in the office to surf the Web, or would have singular access to a computer at home without having to compete with husband or children. If they are married, there is a slim chance of them having the time, either at work or at home, to browse the Internet. Which of the following, if true, most seriously weakens the argument given above?
1) Most of the females rise early in the morning and get ready for their office.
2) Half of the new websites being created are devoted to women's interests.
3) Married women spend more time on computer than spinsters do.
4) Internet browsing does not discriminate on the basis of gender.
5) Competition adds charm to Web browsing.
