What is the best method to find out the number of cars entering a certain garage? A) Asking others, B) counting and recording, or C) measuring.

So here are our choices or different methods. And we want to find out the number of cars entering a garage. So should we ask others how many cars enter the garage? Should we count the number of cars and then record them ourselves? Or do we measure the number of cars entering in a garage?

We could ask somebody, but it might not be accurate. Some may have not seen all of the cars entering the garage. So now, for our last two options, do we count the number of cars or do we measure the number of cars? Measuring would be like a length or a growth and we don’t have that here. We’ll simply have a certain number of cars entering the garage.

Therefore, the best method to find out the number of cars entering a certain garage would be the option B, counting and recording.
