Answer:
A platypus
Explanation:
This is just my opinion, but I think a platypus is weirder than a narwhale. Neither animal is weird but, their how they look has a purpose. A narwhales horn is for self defence, while a platypus' bill is for detecting things near them. A platypus is weird in the way that it is the only mammals to lay eggs. Another reason a platypus is weird is that it has a duck bill, otter feet, and beaver-tail. All those things have a purpose, though I'm not sure what.
A, B and D
All of those would reach mass amounts of people.
<em>Answer</em>:
English is the highest spoken language, about 20% of the entire population speaks it. Second is Mandarine Chinese coming in at about 14%. Depending on where you are located it is best to learn the native language.
A benefit of learning English is that you could meet different people who speak the language and gain more knowledge and social abilities. Another way you could benefit is it gives you a better look at hobbies such as reading, maybe you find a book in English but you can't read it because you don't know English, well because your learning English you can read that book.
I hope this helped!
