Here is a question about this article: Much of Richmond's early architecture was destroyed by the Evacuation Fire in 1865. It is estimated that 25% of all buildings in Richmond were destroyed during this fire. Even fewer now remain due to construction and demolition that has taken place since Reconstruction. In spite of this, Richmond contains many historically significant buildings and districts. Buildings remain from Richmond's colonial period, such as the Patteson-Schutte House and the Edgar Allan Poe Museum (Richmond, Virginia), both built before 1750.
What is the answer to this question: What disaster destroyed many of the early buildings in Richmond?
****
So... Evacuation Fire

The problem: Answer a question about this article:
Feathers require maintenance and birds preen or groom them daily, spending an average of around 9% of their daily time on this. The bill is used to brush away foreign particles and to apply waxy secretions from the uropygial gland; these secretions protect the feathers' flexibility and act as an antimicrobial agent, inhibiting the growth of feather-degrading bacteria. This may be supplemented with the secretions of formic acid from ants, which birds receive through a behaviour known as anting, to remove feather parasites.
What is the process of removing feather parasites?
****
The answer: anting

Two common considerations have the Latin names lectio brevior (shorter reading) and lectio difficilior (more difficult reading). The first is the general observation that scribes tended to add words, for clarification or out of habit, more often than they removed them. The second, lectio difficilior potior (the harder reading is stronger), recognizes the tendency for harmonizationresolving apparent inconsistencies in the text. Applying this principle leads to taking the more difficult (unharmonized) reading as being more likely to be the original. Such cases also include scribes simplifying and smoothing texts they did not fully understand.

Is a lectio brevrio or lectio difficilior approach more akin to the original text?
Answer: Applying this principle leads to taking the more difficult (unharmonized) reading as being more likely to be the original.

Problem: The pitch of complex tones can be ambiguous, meaning that two or more different pitches can be perceived, depending upon the observer. When the actual fundamental frequency can be precisely determined through physical measurement, it may differ from the perceived pitch because of overtones, also known as upper partials, harmonic or otherwise. A complex tone composed of two sine waves of 1000 and 1200 Hz may sometimes be heard as up to three pitches: two spectral pitches at 1000 and 1200 Hz, derived from the physical frequencies of the pure tones, and the combination tone at 200 Hz, corresponding to the repetition rate of the waveform. In a situation like this, the percept at 200 Hz is commonly referred to as the missing fundamental, which is often the greatest common divisor of the frequencies present.
the percept at 200 Hz is commonly referred to as the missing fundamental, which is often?
The answer is the following: divisor of the frequencies present

Input: Article: As a result of the abolition of serfdom and the availability of education to the native Estonian-speaking population, an active Estonian nationalist movement developed in the 19th century.[citation needed] It began on a cultural level, resulting in the establishment of Estonian language literature, theatre and professional music and led on to the formation of the Estonian national identity and the Age of Awakening. Among the leaders of the movement were Johann Voldemar Jannsen, Jakob Hurt and Carl Robert Jakobson.

Now answer this question: Who were the leaders of the Age of Awakening?

Output:
Johann Voldemar Jannsen, Jakob Hurt and Carl Robert Jakobson.
