A graduate student at ____, Cybulski was looking for ways to apply his engineering background to make a difference in the real world.

After hearing Prakash’s ____, Cybulski quickly recognized its potential and was eager to contribute.

For a microscope to function properly, it ____ meet certain minimum requirements.

____ include an eyepiece, a tube through which the viewer looks, and a lens for magnification.

The microscope ____ also have a component that can hold a specimen and move from side to side to explore different areas of the specimen.

Furthermore, a ____ to bring the specimen into focus, usually accomplished by moving it closer to or farther from the lens, is necessary.

Finally, a light ____ is required to illuminate the specimen.

An ideal microscope would be made with the best performing ____ and mechanisms for each component.

However, such a microscope would likely be ____ expensive.

On the other hand, a cheap ____ may not be able to deliver high performance.

Prakash and Cybulski experimented with various designs and materials in order to ____ a suitable compromise.

While many manufacturers might have settled for a middle ground between these two extremes, Prakash and Cybulski were determined to create a microscope that was both inexpensive and ____, while remaining accessible to all.

After drawing various designs on paper, Prakash and ____ realized that paper could be an excellent medium for their microscope.

It was cheap, easy to cut and fold with ____, and widely available.

They faced many challenges during their attempts to ____ the perfect design.

Ultimately, they settled on waterproof cardboard paper with a small glass ____ lens and named their invention the Foldscope.
