reading comprehension 1

[fire fly]

Could anyone help me with the following questions about reading comprehension? Thanks in advance.

Sometimes you know things about people the first time you see them, for example, that you want to be friends with them or that you don’t trust them. But perhaps this kind of intuition isn’t as hard to explain as it may seem. For instance, people give out body language signals all the time. The way you hold your body, head and arms tells people about your mood. If you hold your arms tightly at your sides, or fold them across your chest, people will generally feel that you are being defensive. Holding your head to one side shows interest in the other, while an easy, open posture indicates that you are self-confident .All this affects the way you feel about someone.
Also, a stranger may remind you of a meeting with someone. This may be because of something as simple as the fact that he or she is physically similar to someone who treated you well or badly. Your feelings about a stranger could be influenced by a smell in the air that brings to mind a place where you were happy as a child. Since even a single word can bring back a memory such as that, you may never realize it is happening.

1. Intuition described in the passage can be explained by means of _________
A. signals B. languages C. behaviours D. styles
The answer is “A. signal”. I know that “intuition means “instinct”. I also know that “B, C & D” are incorrect but I can’t make sense of this. Who can give me a clear explanation?

• What one feels about a stranger may be influenced by something that ________
  A. strengthen one’s past behaviours B. reminds one of one’s past treatment
  C. revives one’s past memories D. points to one’s childhood

The answer is “C. revives one’s past memories”. Why not “D. points to one’s childhood.

The way I understand this is, that signal here comprises of all 3: language, behaviour, style. Signal it could be any sign, gesture, sound or action. It's not just one thing that works on our intuition, it could be any of those.

• What one feels about a stranger may be influenced by something that ________
  A. strengthen one’s past behaviours B. reminds one of one’s past treatment
  C. revives one’s past memories D. points to one’s childhood

The answer is “C. revives one’s past memories”. Why not “D. points to one’s childhood.
I think childchood memories are given as a one of the examples of past memories in general. Look at the red part, where it says 'bring back a memory such as that'.
