Beyond humans which is most intelligent mammal?

from my experiences in life, I would argue that perhaps orang-utans are more intelligent than some humans.

This question is badly worded. It should ask "Which mammal is the most intelligent after humans" or "Which is the second most intelligent mammal".

most of them got it wrong lol.. it's orangutan closest spieces to human

Dolphin fans may give you an argument

Why isn’t dolphin on the list? That’s a great wrong answer. Put some thought into the wrong answers.

really!!! have you seen some humans lack of intelligence.
