Success Criteria – I know I am successful when I can select information
from a complex data presentation, understand the methods and tools
used in a moderately complex experiment, and select a simple
hypothesis, prediction, or conclusion that is supported by a data
presentation.
Quick Note!
• Today’s questions are based on the printed
passage you will receive shortly. After reading
your passage individually or as a group,
choose the best answer to each question. You
may refer to the passages as often as
necessary.
• You have 2 Minutes to read your passage!

#2. Based on Student 1’s discussion and Fact 4, while
matter flowed between Algol A and Algol B, Algol B
produced the majority of its energy by fusing:
A. hydrogen nuclei to make helium nuclei at its center.
B. hydrogen nuclei to make helium nuclei in a shell
surrounding its center.
C. helium nuclei to make hydrogen nuclei at its center.
D. helium nuclei to make hydrogen nuclei in a shell
surrounding its center.

#3. Suppose that chemical composition is uniform among
stars formed from the same cloud of gas and dust, but that
chemical composition varies among stars formed from
different clouds of gas and dust. Student 2 would most
likely agree with which of the following statements
comparing the chemical compositions of the stars in the
present-day Algol system at the time they formed?
A. Algol A and Algol B had the most similar compositions.
B. Algol A and Algol C had the most similar compositions.
C. Algol B and Algol C had the most similar compositions.
D. Algol A, Algol B, and Algol C had the same composition.

#5. Which of the following statements best explains
why the reaction described in Fact 3 requires a high
temperature and pressure?
A. All protons are positively charged, and like
charges attract each other.
B. All protons are positively charged, and like
charges repel each other.
C. All electrons are negatively charged, and like
charges attract each other.
D. All electrons are negatively charged, and like
charges repel each other.

#6. Based on Fact 5 and Student 1’s discussion,
which of the 3 stars in the Algol system, if any,
was most likely the first to become an MS star?
A. Algol A
B. Algol B
C. Algol C
D. The 3 stars became MS stars at the same
time.
9th Grade Science
#7. Based on Fact 5, would Student 2 agree that by
the time Algol A stops being an MS star, Algol A will
have spent as much time being an MS star as Algol
B spent being an MS star?
A. Yes, because according to Student 2, Algol A has
always been more massive than Algol B.
B. Yes, because according to Student 2, Algol A has
always been less massive than Algol B.
C. No, because according to Student 2, Algol A has
always been more massive than Algol B.
D. No, because according to Student 2, Algol A has
always been less massive than Algol B.
