Question

multiple choice
neither other neurons nor the outside world.
the outside world.
other neurons.
other neurons and the outside world.

Explanation:

To answer this, we analyze the context (likely about neuron connections). Neurons connect to other neurons (for signal transmission in the nervous system) and interact with the outside world (via sensory input, motor output). So the correct option is:

Neurons communicate with other neurons (via synapses) and interact with the outside world (e.g., sensory neurons detect external stimuli, motor neurons act on the environment), so they connect to both.

Answer:

D. other neurons and the outside world.
