Answer Key:A, B, E, F
Feedback:The rocks actually keep the soil cooler during the day and warmer at
night, so the benefit is reducing soil temperature during the day and increasing
soil temperature at night.
Answer Key:A, B, C, E, F, G
Feedback:The climate was actually cooler than most Polynesian islands
which prevented the growth of certain crops. The wind, limited rainfall and
freshwater, and porous soil made agriculture more challenging.
Answer Key:A, C, D
Feedback:Clearing forests for farmland actually led to decreased rainfall, more
evaporation, and changes in wind patterns. Deforestation by the Han and Roman
Empires had a global impact on methane in the atmosphere.
, Answer Key: A, B, C, D, E, F
Feedback: All of the answers are indicators of productivity, consumption, and
general well-being. The reading argues that the existence of slave labor meant
that the poor class still had enough money that slave labor was cheaper.

Answer Key:False
Feedback:Although this sentiment is true for the middle and late

Throughout all of Roman history, Romans were proud of their ability to alter
nature and deplete natural resources.

Answer Key:A, B, E, F
Feedback:The rocks actually keep the soil cooler during the day and warmer at
night, so the benefit is reducing soil temperature during the day and increasing
soil temperature at night.
Answer Key:B, D
Feedback:Volcanic activity increased in the 530s - 540s CE. Volcanic eruptions
spew reflective sulphates into the atmosphere leading to colder temperatures.
This cold period is called the 'Late Antique Little Ice Age' which lasted at least
150 years. It was detected by dendrochronology and isotopes in ice cores. This
was a peak in climate instability which undermined economic productivity in the
agrarian (agriculture-based) society.
