Respuesta :

The word that is not a signal word for theory or evidence is option C. therefore. The word "therefore" is used to conclude on something that has been proven. Whereas the words "considering, because and for example" are used to show evidence about something that is studied. 

Answer:

B. because

Explanation:

"Because" is not a signal word for theory and/or evidence. The word implies a relationship of cause. It is used when we are giving the reason why something has happened. On the other hand, the other words that are used in the options are all indicative of theory or evidence, as they all allow us to introduce evidence that supports the argument we are putting forward.
