Answer :
The question is asking us to identify the term that best describes "the annual number of deaths per 1,000 members of a population." This term is known as the "mortality rate" or "death rate".
The options given are numbers: 2, 3, 5, and 670910. None of these numbers are words, and none of them inherently represent the concept of a mortality rate without additional context. Mortality rates are typically expressed as a figure, such as 5 per 1,000 people, but without this context the numbers alone do not fit the definition.
Given the options presented, none are correct because the expectation is to select a term that signifies the definition provided, and we are given only numbers, not terms. Thus, there is no correct choice from the list to match the definition of "the annual number of deaths per 1,000 members of a population," which is 'mortality rate' or 'death rate'.
The correct answer would be 'mortality rate' or 'death rate'. However, since these exact terms are not listed among the choices, none of the options provided can be selected as the right answer.
