1.What is an inference?(1 point)
a. the general attitude of a text
b.the special words used in a subject such as art, science, or mathematics
c. a conclusion, based on evidence, about something that is not stated directly in a text
d. the facts and information that support an idea or analysis use the sentence to answer the question. Opals can be worth a lot of money.

2. Which piece of evidence supports this inference? (1 point)

a. Coober Pedy is one of the least accessible towns in Australia—the place where the old American West meets Mars—which is probably why it gained a reputation as the place where outlaws went to hide.

b. In the heat of day, people are nowhere to be found, each hidden in an opal mine or dugout.

c. One of Coober Pedy's most popular destinations, the mine provides visitors with an opportunity to learn about the search for opals and the struggles of Coober Pedy's earlie
