Answer:

A) Determine the average number of times during a week in May that a group of bees visits flowers.

Explanation:

These observations may be mostly qualitative in nature at the real or exploratory stage of a study, but trials are usually done to show them in the form of quantitative data at some later stage. It is important that experimental information must be accumulated and arranged in a sequential fashion and in a form which can be understood by all: ideas may be more easily extracted, and results will be more easily drawn from data which have been arranged into a coherent pattern.
