3. Below is a satellite image of a town in the Amazon Rainforest.
The numbered points along the river were chosen by scientists as various town sites where
the water quality would be tested. They rated the samples, according to several factors, on
a scale from 1 to 10, where 10 is the best water quality. The scientists noted that there was
much less human development (such as homes, factories or roads) around sites 1, 3, and 4.

following areas in town?
A) between sites 2 and 4
B) between sites 5 and 6
C) between sites 6 and 3
D) between sites 3 and 1
4. Refer to the information in question 3.
Beyond Site 1, there is dense, lush rainforest and little development. So little, in fact, that the
scientists were unable to travel there to collect a sample. They have hired you to estimate what
the water quality might be in this undisturbed environment. Based on the collected results, what
would you expect the water quality to be downstream from Site 1? (Give a whole number
estimate.)
5. Refer to the information in question 3.
Many of the townspeople believe that the main cause of the poor water quality at Site 6 is
contamination from the city upstream (not on the map). Based on the results of the water
quality test, is this assumption fair?
A) Yes
B) No
