Based on the graph and the information in the passages, which statement is accurate?

Carbon-14 has a half-life of about 5,400 years.

Which generalization about the study of physics is supported by both passages?

The study of atomic & nuclear physics is used in many fields

In Passage 2, the author refers to an accident...as a "short-term concern" because:

the initial amount of radiation is high but drops quickly

Which choice provides the best evidence for the answer to the previous question?

Lines 27-30 ("Living plants...carbon dioxide").

Based on the information in Passage 2, living tissue exposed to radioactive material can

suffer injury when the cell's components are damaged.

Which choice provides the best evidence for the answer to the previous question?

Lines 38-41 ("Carbon-14 dating...animals").

Which statement best describes the relationship between carbon-12 & carbon-14 in living tissue?

The ratio of carbon-12 to carbon-14 is constant.

According to Passage 2, scientists use the half-life of a radioactive material to determine the

length of time that must pass until an area is safe again.

1
Based on the graph and the information in the passages, which statement is accurate?
Carbon-14 has a half-life of about 5,400 years.
The half-life of iodine-131 is greater than cesium-137.
All radioactive materials have a half-life of 30-5,400 years
The half-life of carbon-14 is similar to that of cesium-137.

9
As used in line 25, "decay" most nearly means:
discharge
yield
circulate
deteriorate
10
According to Passage 2, scientists use the half-life of a radioactive material to determine the
amount of danger posed immediately after a nuclear accident.
amount of radiation contained in a sample of iodine & cesium
length of time that must pass until an area is safe again.
likelihood of an accident releasing radioactive materials.
11
As used in line 75, "original" most nearly means:
critical
unusual
unique
earliest
