Answer:
Two Dutch spectacle-makers and father-and-son team, Hans and Zacharias Janssen, create the first microscope in 1590.
Explanation:
A microscope is an instrument that makes an enlarged image of a small object, thus revealing details too small to be seen by the unaided eye. The most familiar kind of microscope is the optical microscope, which uses visible light focused through lenses. Eeuwenhoek observed animal and plant tissue, human sperm and blood cells, minerals, fossils, and many other things that had never been seen before on a microscopic scale. He presented his findings to the Royal Society in London, where Robert Hooke was also making remarkable discoveries with a microscope.

The type of software which is offered in trial form or for a limited period of time is called shareware.
Software which are offered for free in trial form or for a limited time period are called shareware. They operate on the principle that once the user understands what the software can offer they will pay to use it later.
Most shareware software has built in countdowns which start as soon as you start the trial and at the end of which access is automatically revoked. They require the user to form a simple account. These versions generally provide a very basic selection of functions and are used to rake in more paying users.
Types of shareware include:
- Adware: It stands for advertising-supported software where the advertisements generate revenues.
- Demoware: This is a trial version of the original software including all features.
- Crippleware: This software is free but provides limited features till it is purchased.
- Trialware
This provides the user with full feature access for a time limit and then requires purchase.
