TASK DEFINITION: In this task you will be given a text passage from a trivia quiz. You should choose the category this question belongs to from these categories: History, Science, Social Science, Fine Arts, Literature. You can only choose one category, so if in doubt, please choose the closest match.
PROBLEM: People escaping during this event utilized the McCorkell Line to seek passage to Canada and US. In the country where this took place, it is referred to as ""an Gorta Mor"" or ""an Drochshaol. "" One response to this event was Robert Peel's decision to repeal the Corn Laws. Thought to be caused an oomycete known as Phytophthora infestans, this event resulted in approximately a million deaths. For 10 points, name this massive dying caused by a blight, which affected a particular crop in the 1840's and 50's in Ireland.

SOLUTION: Social Science

PROBLEM: Ninhydrin forms a Schiff base with this chemical, resulting in a hue known as Ruhemanns purple. The Birch reduction takes place in a liquid substrate of it, the reason it is common in methamphetamine labs. The Kjeldahl method uses this molecule as an end-product to measure the amount of nitrogen in a sample, and it is oxidized in the first step of a nitric acid forming procedure, the Ostwald process. For 10 points, name this weak base found in fertilizers, formed by combining hydrogen and nitrogen in a three-to-one ratio in the Haber process.

SOLUTION: Science

PROBLEM: Code and Welch first observed the kind of these structures that emit ultraviolet radiation, challenging popular opinion that they would be dark in that part of the spectrum. Their metallicity is given by the magnesium-sigma relation. Isophotes that describe these structures may feature a twist in them, or a boxy appearance. AGNs that emit radio waves are typically found within these structures, one example of which is M87. They have their surface intensity related to empirical distance via de Vaucouleurs' law. An empirical law modeling the luminosity of these structures is derived from the fundamental plane relation and states that the luminosity is equal to the fourth power of the velocity dispersion, which is known as the FaberJackson relation. For 10 points, identify these galaxies named for their oblate shape.
