L1：
1. What is the lecture mainly about?
Misconceptions about muon detectors in Archaeology
An excavation of an ancient structure using a muon detector
The collaboration between physicists and archaeologists in the development of the muon detector
Benefits that archaeologists can obtain from muon detectors
2. What feature of the muons benefit archaeologists?
Their ability to carry information from outer space
Their ability to break down cosmic rays into smaller particles
Their ability to pass through solid material
Their ability to travel at the speed of light
3. According to the professor, what information can a muon detector provide about the Mayan pyramid?
The temperature inside of the structure
The location of rooms within the structure
The age range of the structure
The types of material used to build the structure
4. Why does the professor discuss damages to archaeological sites?
To describe a benefit of using muon detectors in archaeological study
To explain an accident with a muon detector during a pyramid exploration
To indicate how useful detectors are in restoring damaged sites
To explain why muon detectors were rarely used in the past
5. In what ways are modem muon detectors different from muon detectors used in 1967?（多选题）
They are more economical.
They use less energy.
They are not as large.
They take less time to produce an image.
They can scan in more than one direction.
6. What is the professor’s opinion about the newer muon detectors?
She appreciates the help they provide even though it takes much time to produce
images.
She is afraid that many archaeologists will be unwilling to learn to use them.
She thinks that they have greater potential in areas of science other than archaeology. They provide more accurate information about the age of objects than older detectors did.
