Species B is newly introduced into the ecosystem in 2011. According to the graph, how does the introduction of the species affect species A.

• Species B has no effect on the native species A.

• Species B is a food source for species A increasing the population of the native species A.

• Species B is an invasive species and it alters the balance in the ecosystem.

• Species A is an invasive species and it shares a food source with species B causing species Bto increase in population

Which of the following explains why a [Forever] block is needed in this project to ensure that the VR Robot does not fall off of the Playground?

• The [Forever] block ensures that the VR Robot will drive forward forever and not fall off the Playground.

• The [Forever] block will stop the VR Robot from moving.

• Without the [Forever] block, the condition of the Down Eye Sensor detecting red will only be checked once. The VR Robot will drive forward and fall off the Playground.

• The [Forever] block will check the condition of the Bumper Sensor being pressed.

Which of the following Boolean blocks should be used in the [Repeat until] block to check if the VR Robot's Down Eye Sensor detects red so the VR Robot does not fall off of the Playground?

• The <Near object> block

• The <Pressing bumper> block

• The <Color sensing> block

• The <Drive is done> block
