Input: Read this: Some video compression schemes typically operate on square-shaped groups of neighboring pixels, often called macroblocks. These pixel groups or blocks of pixels are compared from one frame to the next, and the video compression codec sends only the differences within those blocks. In areas of video with more motion, the compression must encode more data to keep up with the larger number of pixels that are changing. Commonly during explosions, flames, flocks of animals, and in some panning shots, the high-frequency detail leads to quality decreases or to increases in the variable bitrate.
Question: What only sends the differences within those pixels and blocks?

Output: macroblocks

Input: Read this: Like other historical languages, Old English has been used by scholars and enthusiasts of later periods to create texts either imitating Anglo-Saxon literature or deliberately transferring it to a different cultural context. Examples include Alistair Campbell and J. R. R. Tolkien. A number of websites devoted to Neo-Paganism and Historical re-enactment offer reference material and forums promoting the active use of Old English. By far the most ambitious project[peacock term] is the Old English Wikipedia, but most of the Neo-Old English texts published online bear little resemblance to the historical model and are riddled with very basic grammatical mistakes.
Question: What Wikipedia project translate Old English texts?

Input: Read this: Treatment of TB uses antibiotics to kill the bacteria. Effective TB treatment is difficult, due to the unusual structure and chemical composition of the mycobacterial cell wall, which hinders the entry of drugs and makes many antibiotics ineffective. The two antibiotics most commonly used are isoniazid and rifampicin, and treatments can be prolonged, taking several months. Latent TB treatment usually employs a single antibiotic, while active TB disease is best treated with combinations of several antibiotics to reduce the risk of the bacteria developing antibiotic resistance. People with latent infections are also treated to prevent them from progressing to active TB disease later in life. Directly observed therapy, i.e., having a health care provider watch the person take their medications, is recommended by the WHO in an effort to reduce the number of people not appropriately taking antibiotics. The evidence to support this practice over people simply taking their medications independently is poor. Methods to remind people of the importance of treatment do, however, appear effective.
Question: What health care provider watches the person take their medications?
