Question

which technology produces high - resolution maps that can see through surface vegetation?
○ lidar
○ dowsing
○ electromagnetic photo fields
○ psychometry

question 69
is dowsing a scientifically approved method to locate underground features?
○ no, because there are not enough professional dowsers yet
○ yes, it has always been correct
○ no, as no controlled trial has ever shown it to be more effective than chance
○ yes, because hard science has backed it up

Explanation:

First Question (Technology for high - resolution maps through vegetation)

LIDAR (Light Detection and Ranging) uses laser light to measure distances and can create high - resolution maps that can penetrate surface vegetation to show underlying terrain or features. Dowsing is a pseudoscientific method for finding water or other substances, not for map - making. Electromagnetic Photo Fields is not a recognized technology for this purpose. Psychometry is related to the measurement of psychological traits, not map - making.

Scientific approval of a method requires controlled trials. Dowsing has never been shown in controlled trials to be more effective than random chance. The number of professional dowsers is not relevant to scientific approval. Claims that it has always been correct or is backed by hard science are not supported by evidence.

Answer:

A. LIDAR

Question 69 (Scientific approval of dowsing)
