Hi,<br/><br/>Consider,<br/><br/>(1) <b>smth is unavailable TO other people/students/citizens</b>, etc.<br/>(2) <b>smth is unavailable FOR other tasks/uses/purposes </b><br/><br/>I guess (1) and (2) are fine (judging by the examples I saw in COCA), but...<br/><br/>Can I also say,<br/>(3) <i>Their service is unavailable FOR me</i>.<br/>(4) <i>These possibilties are unavailable TO other tasks</i>?<br/><br/>Thank you!<br/>mus-te
