◉ A small team of wildlife researchers is working on a project that
uses motion-activated field cameras to capture images of animals at
study sites. The team is considering using a "citizen science"
approach to analyze the images. Which of the following best explains
why such an approach is considered useful for this project?
A
Distributed individuals are likely to be more accurate in wildlife
identification than the research team.
B
The image analysis is likely to be more consistent if completed by an
individual citizen.
C
The image analysis is likely to require complex research methods.
D
The image analysis is likely to take a longer time for the research
team than for a distributed group of individuals.. Answer: D
◉ An algorithm is intended to display the following output.
red red blue red red blue red red blue
,Which of the following code segments can be used to display the
intended output?. Answer: C
◉ In a certain computer program, two positive integers are added
together, resulting in an overflow error. Which of the following best
explains why the error occurs?
A
The program attempted to perform an operation that is considered
an undecidable problem.
B
The precision of the result is limited due to the constraints of using a
floating-point representation.
C
The program can only use a fixed number of bits to represent
integers; the computed sum is greater than the maximum
representable value.
D
The program cannot represent integers; the integers are converted
into decimal approximations, leading to rounding errors.. Answer: C
◉ For which of the following input values will the circuit have an
output of true ?
A
A = true, B = true, C = true, D = false
,B
A = true, B = false, C = false, D = true
C
A = false, B = true, C = true, D = true
D
A = false, B = false, C = true, D = true. Answer:
◉ The following programs are each intended to move the robot to
the gray square. Program II uses the procedure GoalReached, which
returns true if the robot is in the gray square and returns false
otherwise.
Which of the following statements best describes the correctness of
the programs?
A
Program I correctly moves the robot to the gray square, but program
II does not.
B
Program II correctly moves the robot to the gray square, but
program I does not.
C
Both program I and program II correctly move the robot to the gray
square.
D
, Neither program I nor program II correctly moves the robot to the
gray square.. Answer: C
◉ Flight simulation software, which imitates the experience of
flying, is often used to train airline pilots. Which of the following is
LEAST likely to be an advantage of using flight simulation software
for this purpose?
A
Flight simulation software allows pilots to practice landing in a
variety of different terrains and weather conditions without having
to physically travel.
B
Flight simulation software could save money due to the cost of
maintenance and fuel for actual training flights.
C
Flight simulation software provides a more realistic experience for
pilots than actual training flights.
D
Flight simulation software allows for the testing of emergency air
situations without serious consequences.. Answer: C
◉ Which of the following actions are generally helpful in program
development?
Consulting potential users of the program to identify their concerns
