This task is about creating an unanswerable question based on a given passage. Construct a question that looks relevant to the given context but is unanswerable. Following are a few suggestions about how to create unanswerable questions:
(i) create questions which require satisfying a constraint that is not mentioned in the passage
(ii) create questions which require information beyond what is provided in the passage in order to answer
(iii) replace an existing entity, number, date mentioned in the passage with other entity, number, date and use it in the question
(iv) create a question which is answerable from the passage and then replace one or two words by their antonyms or insert/remove negation words to make it unanswerable.

Question: Passage: In the late 19th century with the discovery of the electron, and in the early 20th century, with the discovery of the atomic nucleus, and the birth of particle physics, matter was seen as made up of electrons, protons and neutrons interacting to form atoms. Today, we know that even protons and neutrons are not indivisible, they can be divided into quarks, while electrons are part of a particle family called leptons. Both quarks and leptons are elementary particles, and are currently seen as being the fundamental constituents of matter.

Answer: What field of physics began in the 19th century?


Question: Passage: In contrast to Catholic allegations of rationalism and naturalism, Protestant objections are more likely to be based on allegations of mysticism, occultism, and even Satanism. Masonic scholar Albert Pike is often quoted (in some cases misquoted) by Protestant anti-Masons as an authority for the position of Masonry on these issues. However, Pike, although undoubtedly learned, was not a spokesman for Freemasonry and was also controversial among Freemasons in general. His writings represented his personal opinion only, and furthermore an opinion grounded in the attitudes and understandings of late 19th century Southern Freemasonry of the USA. Notably, his book carries in the preface a form of disclaimer from his own Grand Lodge. No one voice has ever spoken for the whole of Freemasonry.

Answer: What are some Protestant rewards to Freemasonry?


Question: Passage: The aftermath of World War II saw an explosion in the discovery of new classes of antibacterial drugs including the cephalosporins (developed by Eli Lilly based on the seminal work of Giuseppe Brotzu and Edward Abraham), streptomycin (discovered during a Merck-funded research program in Selman Waksman's laboratory), the tetracyclines (discovered at Lederle Laboratories, now a part of Pfizer), erythromycin (discovered at Eli Lilly and Co.) and their extension to an increasingly wide range of bacterial pathogens. Streptomycin, discovered during a Merck-funded research program in Selman Waksman's laboratory at Rutgers in 1943, became the first effective treatment for tuberculosis. At the time of its discovery, sanitoriums for the isolation of tuberculosis-infected people were an ubiquitous feature of cities in developed countries, with 50% dying within 5 years of admission.

Answer:
When was the first effective treatment for Streptomycin discovered?
