How do you "detain" students? From the dictionary:
`
Main Entry: de·tain
Pronunciation: di-'tAn, dE-
Function: transitive verb
Etymology: Middle English deteynen, from Middle French detenir, modification of
Latin detinEre, from de- + tenEre to hold —more at THIN
Date: 15th century
1 : to hold or keep in or as if in custody
2 : obsolete : to keep back (as something due) : WITHHOLD
3 : to restrain especially from proceeding : STOP
synonym see KEEP, DELAY
- de·tain·ment /-m&nt/ noun
`
Do we hold the students in custody?
Do we keep the students as if in custody?
Do we restrain the students from proceeding?
Do we keep or delay the students?
`
How would doing any of these things to students increase the pass rate for
the examination? I don't get it. Sorry! Ask your teacher to explain how
to "detain" students, and how doing that to them increases the pass rate for
the exam. Then repost the problem, explaining what happens to students when
they get detained, and why doing that to them changes the pass rate.
