Explanation:

For Question 47:

• The Terman Intelligence Scale is not a standard widely - used IQ test.
• Spearman's G factor is a theoretical construct in intelligence theory, not a test.
• The Wechsler Adult Intelligence Scale - IV (WAIS - IV) is one of the most commonly used IQ tests in the US for adults.
• The Stanford - Binet Intelligence Scale is also a well - known IQ test, but the WAIS - IV is more commonly used in the adult population in the US context.

For Question 48:

• According to the Diagnostic and Statistical Manual (DSM) and common psychological classifications:
• Profound intellectual disability is typically associated with an IQ range of \(0 - 24\).
• Severe intellectual disability is in the range of \(25 - 39\).
• Moderate intellectual disability is in the range of \(40 - 54\).
• Mild intellectual disability is in the range of \(55 - 69\).

Answer:

Question 47: C. Wechsler Adult Intelligence Scale - IV
Question 48: A. \(0 - 24\); \(25 - 39\); \(40 - 54\); \(55 - 69\)
