What kind of narration is used below, and how do you know:
They were standing under a tree, each with an arm round the other's neck, and Alice knew which was which in a moment, because one of them had "DUM" embroidered on his collar, and the other "DEE." "I suppose they've each got "TWEEDLE" round at the back of the collar," she said to herself. They stood so still that she quite forgot they were alive, and she was just looking round to see if the word "TWEEDLE" was written at the back of each collar, when she was startled by a voice coming from the one marked "DUM."
This is Third Person Limited, because we only know what Alice is thinking and feeling.
