Final answer:
The definition of Time in the context of the question is that it is a measure of change, as it's necessary to observe some change in physical quantity to detect the passage of time, aligning with option B.
Step-by-step explanation:
In reference to the Alpha Phi Alpha poem's mention of Time, we can understand the concept as it is discussed in the realm of physics. The definition of time is that it is a measure of change. Such a definition is based on the observation that time's passage is evident through changes in physical quantities, whether it's a change in the number displayed by a digital clock or the angular position of the Sun in the sky. In essence, time is the interval over which change occurs. Given the information provided, the most fitting answer to what the definition of Time is in the Alpha Phi Alpha poem would be B) Time is a measure of change since every measurement of time involves measuring a change in some physical quantity. Options A, C, and D offer philosophical or cyclic perspectives, but the scientific and measured perspective aligns with B.
