A) It's a waste of time to play music for pets because animals obviously can't understand the songs' words.
Explanation: If we look at the other statements, we can see that they use facts, and are nonobjective. We can see this when it shows a poll, (C) which had over 5000 poll answers, and it gave us the data of 80% thought their pets liked the music. Another statement (D) tells us that dogs don't like a type of music (Heavy metal) because the sounds used seem threatening to dogs. And in (B) it shows that subscribers need to answer a survey about their pet's personality. All of these are statements, except for A, which is an opinion. (Hope this helps)
It is correct because Eleanor Roosevelt did serve in as chair of the United Nations Commission on Human Rights and she was instrumental in creating the universal declaration of human rights.
