Question

drag and drop the correct prefix to complete the word in the sentence.
the scientist used a scope to study objects that were too small to see with the naked eye.
options: 1. macro 2. tele 3. micro

Explanation:

To solve this, we analyze the context: the sentence is about a scientist using a scope to study small objects (too small for naked eye). The prefix "micro-" relates to small (as in microscope, which is used to view microscopic objects). The other prefixes "tele-" (relating to distance, like telescope) and "infr-" (relating to infrared, not for small objects) don't fit. So the correct prefix is "micro-".

Answer:

micro- (the option with "micro" to form "microscope")
