Or having new copies of games cheaper than used with staff pleading with you to buy the used copy, for the points.
That, and the "new" copy is opened.
A rocket is not just its physical construction; there's a huge amount of cost in research, design, testing, and support infrastructure - in the case of SLS
The problem is that in case of SLS, which recycles half of the STS equipment, if you need to do so much extra research, maybe it was a wrong idea from the very start. One of the things I found utterly laughable was the recent engine testing campaign for the limited amount of engines that already flew (and will be thrown away), just because they've decided to run them slightly hotter. These things sum up in a nasty way. You could have designed and developed not one but several new launchers for the total sum of incremental SLS expenses, any of them more prospective than the SLS.
Compared to personal pronoun use, especially in situations with multiple potential referents, "less" and "fewer" have a lesser (heh!) potential for creating confusion because changing one for the other doesn't obviously change the amount or kind of information. Even if the use feels wrong ("there were less people") it's still clear what was meant.
Also, there's nothing implicitly wrong with liberal arts, as mathematics is one of them.
A computer without COBOL and Fortran is like a piece of chocolate cake without ketchup and mustard.
