Final answer:
The word 'close' in CAS is situational and does not refer to a specific distance, making the statement true. 'Suggestion' is closest in meaning to a hypothesis, which is an educated guess. Lastly, wave-particle duality does not apply to macroscopic objects, making that statement false.
Step-by-step explanation:
The word "close" in CAS (Context Action Suggestion) does not mean a specific distance, but is rather situational. This statement is true. The context in which "close" is used will determine what is considered close. For example, an object may appear to be closer than it is due to the type of lens used in a situation.
Regarding the question which of the following words is closest to the same meaning as hypothesis, the correct answer is d. suggestion. A hypothesis is a proposed explanation based on limited evidence as a starting point for further investigation. It isn't yet confirmed as a fact or law and is more than just a formula. Rather, it's a thoughtful suggestion or an educated guess to explain a phenomenon.
For clarity on the concept of accuracy and precision, an example is provided using arrows and a target:
- Accurate and precise: Arrows hit the bull's eye and are close to each other.
- Precise but not accurate: Arrows are close to each other but do not hit the bull's eye.
- Not accurate, not precise: Arrows are neither close to each other nor hitting the bull's eye.
The statement about wave-particle duality existing for objects on the macroscopic scale is false, as this phenomenon typically applies to quantum-scale particles like electrons and photons.
