Problem: Please answer a question about the following article about Brain:
The oldest method of studying the brain is anatomical, and until the middle of the 20th century, much of the progress in neuroscience came from the development of better cell stains and better microscopes. Neuroanatomists study the large-scale structure of the brain as well as the microscopic structure of neurons and their components, especially synapses. Among other tools, they employ a plethora of stains that reveal neural structure, chemistry, and connectivity. In recent years, the development of immunostaining techniques has allowed investigation of neurons that express specific sets of genes. Also, functional neuroanatomy uses medical imaging techniques to correlate variations in human brain structure with differences in cognition or behavior.
Until what century was brain studying mostly anatomical?
A: the middle of the 20th century,


Question: Read this and answer the question

The first recorded European excursions into what is now called Tennessee were three expeditions led by Spanish explorers, namely Hernando de Soto in 1540, Tristan de Luna in 1559, and Juan Pardo in 1567. Pardo recorded the name "Tanasqui" from a local Indian village, which evolved to the state's current name. At that time, Tennessee was inhabited by tribes of Muscogee and Yuchi people. Possibly because of European diseases devastating the Indian tribes, which would have left a population vacuum, and also from expanding European settlement in the north, the Cherokee moved south from the area now called Virginia. As European colonists spread into the area, the Indian populations were forcibly displaced to the south and west, including all Muscogee and Yuchi peoples, the Chickasaw and Choctaw, and ultimately, the Cherokee in 1838.

Which European nationality first explored the Tennessee region?
Answer: Spanish


Problem: In May 2014, Oklahoma Director of Corrections, Robert Patton, recommended an indefinite hold on executions in the state after the botched execution of African-American Clayton Lockett. The prisoner had to be tasered to restrain him prior to the execution, and the lethal injection missed a vein in his groin, resulting in Lockett regaining consciousness, trying to get up, and to speak, before dying of a heart attack 43 minutes later, after the attempted execution had been called off. In 2015, the state approved nitrogen asphyxiation as a method of execution.
What was Clayton Lockett's cause of death?
The answer is the following: heart attack


Next, Spielberg teamed with Star Wars creator and friend George Lucas on an action adventure film, Raiders of the Lost Ark, the first of the Indiana Jones films. The archaeologist and adventurer hero Indiana Jones was played by Harrison Ford (whom Lucas had previously cast in his Star Wars films as Han Solo). The film was considered an homage to the cliffhanger serials of the Golden Age of Hollywood. It became the biggest film at the box office in 1981, and the recipient of numerous Oscar nominations including Best Director (Spielberg's second nomination) and Best Picture (the second Spielberg film to be nominated for Best Picture). Raiders is still considered a landmark example of the action-adventure genre. The film also led to Ford's casting in Ridley Scott's Blade Runner.
Who was responsible for Star Wars?
George Lucas


Input: Roman Republic
As with most ancient civilizations, Rome's military served the triple purposes of securing its borders, exploiting peripheral areas through measures such as imposing tribute on conquered peoples, and maintaining internal order. From the outset, Rome's military typified this pattern and the majority of Rome's wars were characterized by one of two types. The first is the foreign war, normally begun as a counter-offensive or defense of an ally. The second is the civil war, which plagued the Roman Republic in its final century. Roman armies were not invincible, despite their formidable reputation and host of victories. Over the centuries the Romans "produced their share of incompetents" who led Roman armies into catastrophic defeats. Nevertheless, it was generally the fate of the greatest of Rome's enemies, such as Pyrrhus and Hannibal, to win early battles but lose the war. The history of Rome's campaigning is, if nothing else, a history of obstinate persistence overcoming appalling losses.

What was considered a problem in the Roman Republic during its last century?
Output: civil war


Problem: Please answer a question about the following article about Uranium:
The discovery and isolation of radium in uranium ore (pitchblende) by Marie Curie sparked the development of uranium mining to extract the radium, which was used to make glow-in-the-dark paints for clock and aircraft dials. This left a prodigious quantity of uranium as a waste product, since it takes three tonnes of uranium to extract one gram of radium. This waste product was diverted to the glazing industry, making uranium glazes very inexpensive and abundant. Besides the pottery glazes, uranium tile glazes accounted for the bulk of the use, including common bathroom and kitchen tiles which can be produced in green, yellow, mauve, black, blue, red and other colors.
Who isolated radium in uranium ore?
A:
Marie Curie
