Question: I want to test the ability of students to read a passage and answer questions about it. Could you please come up with a good question for the passage "Once regarded as plants constituting the class Schizomycetes, bacteria are now classified as prokaryotes. Unlike cells of animals and other eukaryotes, bacterial cells do not contain a nucleus and rarely harbour membrane-bound organelles. Although the term bacteria traditionally included all prokaryotes, the scientific classification changed after the discovery in the 1990s that prokaryotes consist of two very different groups of organisms that evolved from an ancient common ancestor. These evolutionary domains are called Bacteria and Archaea."?
Answer: If a scientist looks at a cell and is unable to spot a nucleus under a microscope, what can they be certain the cell isn't?

Question: I want to test the ability of students to read a passage and answer questions about it. Could you please come up with a good question for the passage "On 13 December 1904, Hungarian Sandor Just and Croatian Franjo Hanaman were granted a Hungarian patent (No. 34541) for a tungsten filament lamp that lasted longer and gave brighter light than the carbon filament. Tungsten filament lamps were first marketed by the Hungarian company Tungsram in 1904. This type is often called Tungsram-bulbs in many European countries. Filling a bulb with an inert gas such as argon or nitrogen retards the evaporation of the tungsten filament compared to operating it in a vacuum. This allows for greater temperatures and therefore greater efficacy with less reduction in filament life."?
Answer:
What did Sandor and Franjo invent?
