What made Martin Luther effective in his speech as far as his delivery?

He was able to speak clearly and tell the audience the message.

answer: sure

explanation: i'd love to know everything but that burden is too much to bare.

the pronoun reference replaces a noun, but you have to make sure there's no room for confusion.

in the first sentence "her" could be referring to shely or to the sister. the answer there is "shelly called her sister and told her about the new baby."

in the second sentence "it" could be referring to the roof or the floor. the answer there is "since the roof leaks on the family room floor, we need to repair the roof."
