15 i'm stuck on this : ( asap!

an author claims that "zoos do more good than harm." the author provides the following as support for the claim:

in 2012, the well-respected research firm martin and associates conducted a study on the request of animal rights activists. the published report was overwhelmingly one-sided. head researcher adeline moreno summed up the results by stating, "the importance of zoos cannot be overstated. the economic and educational benefits for humans are great. the protection and preservation of endangered species is even greater."

which choice best describes the support the author provides?

it is effective support for the claim.
it is ineffective support because it does not prove the claim.
it is ineffective support because it presents opinion rather than fact.
it is ineffective support because it provides no source for the information.

i feel like it's a, but i'm not totally sure.

The choice that best describes the support the author provides is option A, it is effective support for the claim.

I hope this helped you out! Please mark Brainliest if it did!

1. read the following excerpt from franklin d. roosevelt's "fireside chat 19":

on the other side of the picture, we must learn also to know that guerilla warfare against the germans in, let us say serbia or norway, us; that a successful russian offensive against the germans us; and that british successes on land or sea in any part of the world strengthen our hands.

remember always that germany and italy, regardless of any formal declaration of war, consider themselves at war with the united states at this moment just as much as they consider themselves at war with britain or russia. and germany puts all the other republics of the americas into the same category of enemies. the people of our sister republics of this hemisphere can be honored by that fact.  

the true goal we seek is far above and beyond the ugly field of battle. when we resort to force, as now we must, we are determined that this force shall be directed toward ultimate good as well as against immediate evil. we americans are not destroyers — we are builders.
