With an answer, okay . Which one is best, david . Well, youre wrong. The stapler is not best. Jack, which one is best . I like wrong again. It is the the right answer is the binder clip. The binder clip is in my opinion the best. All right . I will admit if i had a 100 page document to fasten, the bientder clip would be best, stapler is not going to do the job very well. On the other hand, if i want to fasten a receipt to a note, maybe i need the paper clip. In effect, i think im coming around to oshas answer. Depends on what were talking about here. The rest are perhaps not obsolete. After all, the author is a cyclist, but no comparison to these things. I would guess if i have to reduce my claim to a thesis its that, wrong, turns out each one of these things has its place and more, and you guys are coming up with more stuff all the time. Electric bicycles, for example. Or high bus rapid transit, which we have dedicated bus lanes for buses to go faster. All kinds of things are possible
