1. What does the professor mainly discuss?
Similarities among historical monsoon data from different sources
The importance of tree-ring dating for understanding the history of ancient cultures
The discovery of a factor that influences climate in Asia and the United States
Work done by scientists to create a model explaining monsoon pttrers
2. According to the professor what is a itaton of using measurement made by mreleogica nstuments when developing a monson mode?
The nstuments used to make measurements in the past were no preiese
The time period hat the measurements cover is limited.
The range of climate variables measured by the measurements is nrow.
Measurements that predate global climate change are useless.
3. Why did the researchers prefer tree-ring dating to collecting information from
cave deposits?
Cave formations only provide data on major climate changes.
Trees are more sensitive than cave formations to rainfall changes.
Caves are found in fewer locations than tees are found.
Information obtained from tree rings goes back further in time.
4. According to the professor, why was the MADA created?
To provide a comprehensive spatial and temporal representation of past monsoons
To compare Asian data to data recorded in the North American Drought Atlas
To prove that tee-ring dating is as accurate as other dating methods
To demonstrate that monsoon patterns 700 years ago were different from monsoon patterns today
5. Why does the professor mention weather conditions in seventeenth-century China?
To point out a previously unknown drought in Asia’s past
To illustrate the validity of data collected for the MADA
To give an example of monsoon areas the MADA does not cover
To explain why predicting Asian monsoons is important
6. What is the professor’s opinion about the effects of global climate change on
predicting monsoons?
Scientists will be able to predict monsoon activity only in some regions.
It will be impossible to predict monsoons until the climate becomes stable again.
Climate change will not limit scientists’ ability to predict monsoon activity.
Climate change makes it easier to create accurate weather models.
