Question: Question: I am just wondering about the difference between: in contrast to and in contrast with 
Answer: Eilia's and user239892's answers ARE correct: after 'in' we say 'in contrast to' but if we use contrast as a verb, we always use 'contrast with'. e.g. Your answer contrasts with Bill's. The third answer is wrong, in contrast to the first two.

Answer: no


Question: Question: Do the English have an ancient (obsolete) verb for the action of the book opening? For example, in Russian we say otkrit' (open the book), but in the Old slavonic the verb razognuti (to unbend the book) was used. 
Answer: The Middle English verb undon was often applied to opening a book (and many other objects). c1300 SLeg.Fran.(1) (LdMisc 108)159 : He on-dude e bok and e furste at he cam to at was a godspel. (He undid the book and the first that he came to - that was a gospel.) a1325 SLeg.(Corp-C 145)354/166 : Hewende him sulf for is wei & e oer vndude e bok. (He walked himself forth his way and the other undid the book.) c1475 Mankind (Folg V.a.354)797 : All e bokys in e worlde, yf ei hade be wndon, Kowde not a cownselde ws bett. (All the books in the world, if they had been undone, could not have counseled us better.) This meaning has since disappeared along with the book clasps that would have once been common on books. (To see a few examples of bindings, see "Medieval bindings" on the British Library site.).

Answer: no


Question: Question: Possible Duplicate: "Toward" or "towards"? Which is the correct usage? "Onwards" or "Onward" ? For example: I would be free any time Tuesday onward. vs I would be free any time Tuesday onwards. Or is both correct/wrong? The spell checker in my browser says onwards is wrong but I've heard people using it. (p.s: Sorry if this question is redundant. I searched here but couldn't find a related question) 
Answer: Apparently, there is a slight difference, but only in British English: Note: In British English, 'onwards' is an adverb and 'onward' is an adjective. In American English and sometimes in formal British English, 'onward' may also be an adverb. So, depending on where you are, the difference maybe slight. However, they both mean the same thing practically, and most people will understand you if you use either anyways.

Answer:

Show your work and conclude with the exact phrasing "Therefore, the final answer is [answer]." where [answer] is just the final number or expression that solves the problem.
