Success Criteria – You know you are successful when
you can compare data from a simple data
presentation, interpolate between data points in a
table or graph, and select a prediction that is
supported by a data presentation.
Please Note
• You have 4 Minutes to read your passage.
• You will have 1 minute and 15 seconds to
work on each question individually.
• You will have 1 minute and 30 seconds to
work as a group and write your rationales for
each answer.

#1. Based on the results of Study 4, how did fragmentation
most likely affect the population sizes of insectivores and
hummingbirds in the fragments studied?
A. Fragmentation increased the population sizes of both
insectivores and hummingbirds.
B. Fragmentation decreased the population sizes of both
insectivores and hummingbirds.
C. Fragmentation increased the population size of
insectivores and decreased the population size of
hummingbirds.
D. Fragmentation decreased the population size of
insectivores and increased the population size of
hummingbirds.

#2. Based on the results of Study 1, if the distance
from the center of a 100 m x 100 m plot were 75 m
from the nearest clearing, the expected average
change in AGTB at the plot over 17 yr would be
closest to which of the following values?
A. -1.1 t/yr
B. -2.6 t/yr
C. +1.1/yr
D. +2.6 t/yr

#3. After examining the results of Study 2, a
student concluded that the AGTB at each of the
25 plots remained constant. Which of the
following alternative explanations is also
consistent with the results?
A. The AGTB at all 25 plots increased.
B. The AGTB at all 25 plots decreased.
C. The AGTB at some of the plots increased and the
AGTB at some of the plots decreased.
D. The AGTB at plots bounded by forest increased and
the AGTB at plots bounded by clearings remained
constant.

• Repeat the questions with your squad
members. Be sure to write a rationale. If
you don’t write a rationale, you won’t learn
as much. Your brain is like a muscle. Use it!
• 1 minute and 30 seconds per question for
Squad Mode.
• After the rationale writing is done, launch the
Answers video.
