Read the scenario.

A biologist is studying golden frogs that live in cool streams running through the rain forests of Central America. The biologist conducts a survey of the population and counts over 100 frogs in one mile of stream. The biologist returns to the same location one year later and counts only 20 frogs in that same stretch of stream. The biologist wonders why there are suddenly so few golden frogs.

The biologist also observes that a mining company has set up a copper mine only a few miles from the stream. By reading studies on copper mining operations in other parts of the world, the biologist learns that the wastewater runoff from the mines is highly acidic and contains potentially toxic compounds.

Which part of the scientific method is best illustrated by the biologist wondering why there were so few frogs in the second year compared to the first?

a making an observation and asking a question

b collecting data

c setting up an experiment

d forming a hypothesis

Making an observation and asking a question is a part of the scientific method that is best illustrated by the biologist wondering why there were so few frogs in the second year compared to the first. Thus, the correct option is A.

What is the Scientific method?

The scientific method may be defined as the procedure of objectively confirming attributes through testing and experimentation. It includes observation, hypothesis, prediction, operating an experiment, and finally investigating the results.

A biologist collected the data on the frog population before industrialization, but after a year there should be a considerable reduction in the population of frogs observed by a biologist. The cause of it is also determined by the biologist very well.

Therefore, the correct option for this question is A.
