With the advance of science, there has been a tendency to slip into scientism, and assume that any factual claim can be authenticated if and only if the term ‘scientific’ can correctly be ascribed to it. The consequence is that non-scientific approaches to reality ― and that can include all the arts, religion, and personal, emotional and value-laden ways of encountering the world ― may become labelled as merely subjective, and therefore of little account in terms of describing the way the world is.
Q1. In the above passage, what does "it" indicate? Is that "factual claim"? Am I right?
Q2. Shouldn't "that" be changed to "those"? I think the "that" is supposed to mean "non-scientific approaches to reality" and "approaches" are plural form. So the plural form of pronoun, "those" is needed here. Am I right or wrong?
