77. Give at least three examples of palindromic English words (written the same forward and backwards), each at least four letters long.
78. Six extremely obese [women](woman.md) ([Rust](rust.md) developers) -- three normal and three lesbian -- want to get to a party that's in the sixth floor of a building. As they are morbidly obese using stairs is not an option, they have to take the lift. The lift is on the ground floor but its outside button is broken, it can only ride if there is at least one human inside it who controls it (and it also doesn't go to any other floor than the two), but it also cannot carry more than two women at once (remember, they are obese). Lesbian must never outnumber the normal women otherwise they wouldn't be able to control themselves and would rape them. The women are too dumb to solve the problem of how to get to the sixth floor without any rape happening, they call you to help them -- find a solution to this.
79. Does 0.999... (infinitely many 9s) equal 1?
80. Did you enjoy this quiz?
80. If [capitalism](capitalism.md) is bad why are people migrating into capitalist countries such as [USA](usa.md)?
81. Why are low quality videos "blocky"?
82. What's the next number in the following sequence? 0, 1, 5, 19, 65, 211, 665, 2059, 6305, 19171, 58052, ???

77. For example: poop, boob, civic, deed, level, rotor, madam, refer, stats etc.
78. For example (`L` = lesbian, `N` = normal): `LLLNNN *|` -> `NNNL |* LL` -> `NNNLL *| L` -> `NNN |* LLL` -> `NNNL *| LL` -> `NL |* NNLL` -> `NNLL *| NL` -> `LL |* NNNL` -> `LLL *| NNN` -> `L |* NNNLL` -> `LL *| NNNL` -> `|* NNNLLL`.
79. yes (look it up)
80. yes
80. For the same reason mosquitoes fly into the mosquito killer lamps -- they have microscopic brains.
81. Possibly for several reasons but the most prominent one is likely that video codecs typically try to save space by not saving every frame of the video as a picture but rather encode movements of small blocks into which keyframes (static pictures saved at relatively low "FPS") are chopped. This exploits temporal redundancy -- the fact that frames close in time are similar to one another, i.e. that knowing one frame we can most likely get approximate version of the next frame by splitting the current frame into blocks and just moving them around a bit. Of course this doesn't work perfectly and low bitrate or nontypical scenes can make the blocks highly visible. It would be possible to come up with similar methods that don't use blocks and may look prettier but rectangular blocks of pixels are very easy and fast to work with and the results look good enough, so they are usually used. Another reason for blockiness of videos may be e.g. that the keyframes themselves are compressed with some lossy JPEG-like compression that makes them "blocky".
82. 175099, formula for the series is *3^n - 2^n*.
83. yes
