Explanation:

For the first question: A compound microscope uses two sets of lenses (eyepiece/ocular and objective lenses) to magnify images. A simple microscope only uses one lens, an electron microscope uses electron beams instead of visible light and glass lenses, and "complex microscope" is not a standard term.
For the second question: The revolving nosepiece (turret) on a microscope is the component that holds the objective lenses, allowing the user to switch between different magnification objectives. The ocular is the eyepiece at the top, and the condenser is a lower component that focuses light on the specimen.

Answer:

1. Compound microscope
2. (Note: The correct option for Question 27 is missing from the provided image, but the revolving nosepiece holds the objective lenses. Based on standard microscope parts, the intended correct answer would be the objective lenses, which is not listed in the visible options.)
