Evidence of former life is called a
a. ghost.
b. fossil.
c. history.
d. relic.

From the following options, the evidence of former life is:
ghost.
fossil.
history.
relic.
Answer to Problem 1AC
Solution:
Option (b) is the correct answer.
Explanation of Solution
Introduction:
Fossils provide the evidence of the events that have occurred in the history of the earth and the evolution of life.
Explanation:
Reason for correct option:
The word fossil originally meant anything dug up from the earth but now days it’s meaning has been changed to that and it gives the evidence of ancient organism, embedded in a rock for a long time.
Hence, option (b) is correct.
Reason for incorrect option:
Option (a) is incorrect because the word ghost does not show any evidence of life.
Option (c) is incorrect because it is due to the fossil the evidence of the ancient organism’s history is known.
Option (d) is incorrect because relic is another word for artefacts which can be any age.
Hence, options (a), (c) and (d) are incorrect options.
Conclusion:
The evidence of former life is obtained from a fossil.
