Input: Brain
In the 21st century, these trends have continued, and several new approaches have come into prominence, including multielectrode recording, which allows the activity of many brain cells to be recorded all at the same time; genetic engineering, which allows molecular components of the brain to be altered experimentally; genomics, which allows variations in brain structure to be correlated with variations in DNA properties and neuroimaging.

Genetic engineering was first discovered in what century?
Output: the 21st century,

Input: Data compression
Because interframe compression copies data from one frame to another, if the original frame is simply cut out (or lost in transmission), the following frames cannot be reconstructed properly. Some video formats, such as DV, compress each frame independently using intraframe compression. Making 'cuts' in intraframe-compressed video is almost as easy as editing uncompressed video: one finds the beginning and ending of each frame, and simply copies bit-for-bit each frame that one wants to keep, and discards the frames one doesn't want. Another difference between intraframe and interframe compression is that, with intraframe systems, each frame uses a similar amount of data. In most interframe systems, certain frames (such as "I frames" in MPEG-2) aren't allowed to copy data from other frames, so they require much more data than other frames nearby.

What copies data from one frame to another?
Output: interframe compression

Input: Dialect
Modern standard Italian itself is heavily based on the Latin-derived Florentine Tuscan language. The Tuscan-based language that would eventually become modern standard Italian had been used in poetry and literature since at least the 12th century, and it first became widely known in Italy through the works of authors such as Dante Alighieri, Giovanni Boccaccio, Niccolo Machiavelli, and Petrarch. Dante's Florentine-Tuscan literary Italian thus became the language of the literate and upper class in Italy, and it spread throughout the peninsula as the lingua franca among the Italian educated class as well as Italian traveling merchants. The economic prowess and cultural and artistic importance of Tuscany in the Late Middle Ages and the Renaissance further encouraged the diffusion of the Florentine-Tuscan Italian throughout Italy and among the educated and powerful, though local and regional languages remained the main languages of the common people.

From what region of Italy did Florentine Tuscan derive?
Output: Tuscany

Input: Antenna (radio)
The actual antenna which is transmitting the original wave then also may receive a strong signal from its own image from the ground. This will induce an additional current in the antenna element, changing the current at the feedpoint for a given feedpoint voltage. Thus the antenna's impedance, given by the ratio of feedpoint voltage to current, is altered due to the antenna's proximity to the ground. This can be quite a significant effect when the antenna is within a wavelength or two of the ground. But as the antenna height is increased, the reduced power of the reflected wave (due to the inverse square law) allows the antenna to approach its asymptotic feedpoint impedance given by theory. At lower heights, the effect on the antenna's impedance is very sensitive to the exact distance from the ground, as this affects the phase of the reflected wave relative to the currents in the antenna. Changing the antenna's height by a quarter wavelength, then changes the phase of the reflection by 180, with a completely different effect on the antenna's impedance.

Where will the additional current be induced?
Output:
antenna element
