old machine, new answers
physical science subject: relationships of force and motion
in 1900, divers combing the ocean floor in search of sea sponges stumbled upon an old shipwreck. it contained numerous treasures dating back to ancient greece. one treasure was a clocklike tool used in astronomy. with the help of advanced technology, researchers from britain, greece, and the united states discovered that the device was not only used for astronomy. it was also used for tracking the dates of the ancient olympic games.
this ancient device is believed to be about 2,000 years old. due to decay, it did not appear to be of great importance when it was first discovered. then, it was brought to a museum in athens. there, the tool began to dry and break apart. as this happened, it began to show its elaborate interior.
the tool was found over a century ago. however, details about the inner workings of the device have been discovered only within the past few decades. this was thanks to advances in technology.
in the 1900s, researchers used x - ray technology to determine that the device was an
question 1
what is a cause - and - effect relationship that takes place in the article?
a. scientists needed an x - ray scanner to study the device in 2005 because the inside was full of bronze gears.
b. since the device is over 2,000 years old, some think it could be used to study the ancient olympic games.
c. scientists are unclear about how the device was used for astronomy because it is corroded on the inside.
d. since the device has words from sicily on it, some think it could be modelled after one archimedes built

Explanation:

• Option A: The text does not mention that scientists needed an x - ray scanner because the inside was full of bronze gears.
• Option B: The text states that the device was used for tracking the dates of the ancient Olympic Games, and since it is over 2000 years old, it could be used to study the ancient Olympic Games. This shows a cause - and - effect relationship.
• Option C: The text does not say that scientists are unclear about how the device was used for astronomy because it is corroded on the inside.
• Option D: The text does not mention that the device having words from Sicily on it is the reason some think it could be modeled after one Archimedes built.

Answer:

B. Since the device is over 2,000 years old, some think it could be used to study the ancient Olympic Games.
