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?

• Distributed individuals are likely to be more accurate in wildlife identification than the research team.

• The image analysis is likely to be more consistent if completed by an individual citizen.

• The image analysis is likely to require complex research methods.

• The image analysis is likely to take a longer time for the research team than for a distributed group of

  individuals

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?

• Code A

• Code B

• Code C

• Code D

TThe diagram below shows a circuit composed of three logic gates. Each gate takes two inputs and produces a

single output.

For which of the following input values will the circuit have an output of true ?

• A = true, B = true, C = true, D = false

• A = true, B = false, C = false, D = true

• A = false, B = true, C = true, D = true

• A = false, B = false, C = true, D = true

The question below uses a robot in a grid of squares.

Which of the following statements best describes the correctness of the programs?

• Program I correctly moves the robot to the gray square, but program II does not.

• Program II correctly moves the robot to the gray square, but program I does not.

• Both program I and program II correctly move the robot to the gray square.

• Neither program I nor program II correctly moves the robot to the gray square.

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?

• Flight simulation software allows pilots to practice landing in a variety of different terrains and weather

  conditions without having to physically travel.

• Flight simulation software could save money due to the cost of maintenance and fuel for actual training

  flights.

• Flight simulation software provides a more realistic experience for pilots than actual training flights.

• Flight simulation software allows for the testing of emergency air situations without serious consequences.

Which of the following actions are generally helpful in program development?

I. Consulting potential users of the program to identify their concerns

II. Writing and testing small code segments before adding them to the program

III. Collaborating with other individuals when developing a large program

• I, II, and III
• I and II only

• I and III only

• II and III only

Which of the following statements correctly explain how the Internet is able to facilitate communication at a

large scale?

I. A central monitoring computer is used to track and maintain the connections of the Internet.

II. Data is routed between points in multiple ways so that if a connection fails, the data can be rerouted

around the inoperative connections.

III. Protocols for packets and routing are used so that computers from different manufacturers can

communicate in a standard way.

• I, II, and III
• I and II only

• I and III only

• II and III only

An Internet user has a need to send private data to another user.

Which of the following provides the most security when transmitting private data?

• Certifying the data with a Creative Commons license before sending it

• Sending the data using a high-bandwidth connection

• Sending the data using public-key encryption

• Sending the data using redundant routing

Ticket prices for a science museum are shown in the following table.

A programmer is creating an algorithm to display the cost of a ticket based on the information in the table. The

programmer uses the integer variable age for the age of the ticket recipient.

The Boolean variable includesTour is true when the ticket is for a guided tour and is false when the ticket is for general admission.

Which of the following code segments correctly displays the cost of a ticket?
