Answer:
Just read your lessons and understand them well you'll get the answer because some of us don't usually know what's the answer, if some of you read this and might say why do i have to answer this even though i don't know what's the answer it's because i have to remind all of you we have some mind we brain we can use we will understand the lesson if we just simply read it and the better way is to understand it very very clear. Don't expect that brainly can handle things you don't understand or if it just your laziness.
Learn your own Lesson. God Bless all of you and thank you ^_^
