While preparing a presentation on historical scientific instruments, a student took the following notes:
* The astrolabe is a flat, portable two-dimensional instrument used to calculate the positions of the Sun and stars.
* Due to its portable design, the astrolabe was widely used for maritime navigation.
* The torquetum is a three-dimensional instrument composed of a complex stack of nested plates, dials, and rings.
* The torquetum was designed to take measurements across three coordinate systems.
* Because the torquetum was bulky and delicate, its use was restricted to land-based observatories.
* Both instruments were widely used by astronomers in the medieval Islamic world and Europe.
The student wants to contrast the physical design and primary usage locations of the astrolabe and the torquetum. Which choice most effectively uses information from the given notes to accomplish this goal?
- Unlike the flat and portable astrolabe, which was widely used for navigation at sea, the torquetum is a complex, three-dimensional instrument whose bulky design restricted its use to land-based observatories.Cevap
- BBoth the astrolabe and the torquetum were widely used by medieval astronomers in Europe and the Islamic world to study the positions of the Sun and stars.
- CAlthough the astrolabe is a two-dimensional analog calculator used for calculating the positions of the Sun and stars, the torquetum was designed to measure celestial coordinates across three distinct systems.
- DBecause the torquetum was a bulky, three-dimensional instrument, it could only be used by astronomers working in land-based observatories rather than at sea.
