These two example web sites both aim to tell you how to cure hiccups.
Have a look at each one and think about the aims.
Web site 1:This web site doesn't really achieve the aim because it tells you about hiccups but not how to get rid of them.
Web site 2:
This site gives you some ways of curing hiccups. So it does achieve the aim. If a site does not do what it says it will then it will be of little use to you
