 (right).
 
 The main difference is that in the case of user-level threading, the operating
-system (os) does not now anything about the user threads. In the concrete
+system (os) does not know anything about the user threads. In the concrete
 example, only a **single** user thread can run at any given time, whereas in
 the case of os-level threading, all threads can run truly parallel.
