Input: Read this: Sub- and quotient groups are related in the following way: a subset H of G can be seen as an injective map H G, i.e. any element of the target has at most one element that maps to it. The counterpart to injective maps are surjective maps (every element of the target is mapped onto), such as the canonical map G G / N.y["] Interpreting subgroup and quotients in light of these homomorphisms emphasizes the structural concept inherent to these definitions alluded to in the introduction. In general, homomorphisms are neither injective nor surjective. Kernel and image of group homomorphisms and the first isomorphism theorem address this phenomenon.
Question: What two forms must homomorphisms take?

Output: unanswerable

Input: Read this: 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.
Question: What was the first treatment of drugs?

Output:
unanswerable
