Many astronomers took up the challenge posed in this work, namely to develop alternate models that resolved these difficulties.

It was an alternate model with larger key pad, controls, and trigger to accommodate the size of his hand.

Q. How did you arrive at your alternate model for the immune system?

In practice few of these are actually valid and alternate models need to be used.

The "alternate models" are replaced with pictures from various horror films and Japanese demons/folklore.

The time and memory consumption of these alternate models may vary.

Many astronomers took up the challenge posed in this work, namely to develop alternate models that evaded such errors.

Then I thought of an alternate model.

Individual studies, alternate models, and earlier versions of the industry consensus have produced other risk estimates scattered around this consensus model.

This alternate model follows the same key points, with slightly more emphasis on personal responsibility.
