Teacher:You are given a passage. You need to construct a question about the information present in the passage. Construct a question in such a way that (i) it is unambiguous, (ii) its answer is the whole paragraph. Avoid creating questions that can be answered correctly without actually understanding the paragraph.
Teacher: Now, understand the problem? Solve this instance: go to yahoo groups and search for something popular (like "Funny" )
and join a group thats has no mail moderation
(in the groups homepage see "Settings" in the left narrow column)
if messages don't need approval then join

this means that anyone can send anything and they r not filtered

spammers use this way in Yahoo! Groups
Student:
Where can I sign an email address up for the most spam possible?
