"look AT the picture (number) 2" is correct

Greetings, See:- When you see something effortlessly or randomly. Look :- When you pay attention. It is kind of affirmative . The write answer is :- Look at . Hope it helps. Regards, Deepika Mantra

In Chinese, see means "看到"； look at means "看"。See that bird? 看到那只鸟了吗？Look at that bird? 看那只鸟。（Focus on the bird）.
