Darius Is Designing a New Type of Self-Driving Automobile Guidance

question 47

Multiple Choice

Darius is designing a new type of self-driving automobile guidance system.He explains to Janelle,his supervisor,that it has far more accurate sensing capabilities than current models,uses current satellite technology used in available guidance systems,can readily be implanted in experimental cars at his company's test facility,incorporates five times as many features and complicated circuitry as current models,and can be easily manufactured by tweaking existing production machinery.Janelle says it is a good start,but she has some concerns.Why is Janelle most likely concerned?

• A)The new model lacks a great advantage over its predecessor.
• B)Darius's model is incompatible with existing infrastructures and processes.
• C)Darius's model has must greater complexity than its predecessor.
• D)Darius's model can only be tried or tested easily with significant cost.
• E)The new model lacks the ability to be copied easily.

Definitions:

Excitatory Neurotransmitter

A type of neurotransmitter that promotes the generation of an electrical signal called an action potential in receiving neurons.

Glutamate

An amino acid that functions as the major excitatory neurotransmitter in the vertebrate brain

All-Or-None Response

The principle that no variation exists in the strength of a single action potential; only a stimulus strong enough to depolarize the membrane to its critical threshold level results in transmission of an action potential.

Depolarized

A state in which the membrane potential of a neuron is less negative compared to the resting potential, easing the initiation of an action potential.
