Poll 2 on the validity of a more complex argument

Is the argument valid?

  • Total voters
  • Poll closed .
I don't use the word "term" in the OP.
A term is a word or expression with a specific meaning, especially one which is used in relation to a particular subject: "Myocardial infarction is the medical term for a heart attack."
All the words I used are to be understood on the basis of an English dictionary.
For example, "logic". What's not to understand?
Here is the argument again:
For all we know, A may be the state of some unknown part of B;
C is determined by the state of some unknown part of B;
Therefore, for all we know, C may be determined by A
All the terms such as "state", "determine", "unknown", "part" etc. are to be understood in their ordinary senses as given by an English dictionary.
A, B and C are to be understood as variables that can stand for and may be substituted with any specific term, such as "wave", "traffic light", "conscious mind" etc.
what parts of the brain are "unknown" ?
Logic is a method of reasoning that involves a series of statements, each of which must be true if the statement before it is true.
I hope this is good enough for you.
