Final answer:
Both discrete trial instruction and naturalistic teaching strategies are true established treatments for developmental disorders, a learning disability is a neurological disorder, and it's false that scientific theories become laws over time. Also, the statement that there are two types of interference, constructive and destructive, is true.
Step-by-step explanation:
Both discrete trial instruction (DTI) and naturalistic teaching strategies are indeed established treatments for individuals with developmental disorders. This makes the statement, "Both discrete trial instruction and naturalistic teaching strategies are established treatments for developmental disorders" A) True.
A learning disability is defined as b) a neurological disorder. These disorders can impact one's ability to understand or use spoken or written language, perform mathematical calculations, coordinate movements, or direct attention.
Regarding the scientific method, the statement "When a theory has been known for a long time, it becomes a law" is B) False. Scientific laws and theories are distinct types of knowledge and one does not become the other simply over time.
The correct statement about the types of interference in physics is: The two types of interference are constructive and destructive interferences, thus the claim is A) True.
