Because the recycling of glass is not typically cost-effective, there is a shortage of glass recycling facilities and glass recycling is not an obligation we all bear. So some people ought not to recycle glass. Which one of the following arguments contains a flaw in reasoning most similar to that in the argument above? ['It is false that you should break your promise, so you do not have an obligation to break your promise.', 'Some convention participants do not have to register on the first day of the convention since their flights were delayed past midnight. So some participants should not register on the first day of the convention.', 'Because operating museums is so expensive, the government can no longer afford to support them. So private foundations that can afford to do so have an obligation to provide the financial support that the government previously provided.', 'Anyone who rides a bicycle at night ought not to ride on a highway. So we ought not to bike on the highway during our trip today.']
