Felsőfú ECL nyelvvizsgán mit mondjak az állatkísérletkről és a nukleáris kísérletekről?

lol maybe you should start with pro/cons:

pro: you can imporove medicines whatsoever by testing them on animals (e.g. rats or mice) coz you can see the actual biological process and outcome (e.g. if the mouse dies, don't try it on humans - just an idea).

cons: it's not approved by many members of the society whatsoever, ehtical issues blah blah blah.

nuclear experiments: same, pro/cons then decide which is closer to you and try to make intelligent conversation about it.

btw if you should ask what to tell about these topics you either should start reading national geographic or similar scientific papers in english or just get some common sense. if you learn some extra words it won't hurt your vocab either..
