What is the correct answer in the following?
Bowling involves 10 frames. Each frame starts with 10 pins. The bowler has two throws to knock all 10 pins down. The total score is the sum of pins knocked down, with some special rules. For the first 9 frames: If all 10 pins are knocked down on a frame's first throw (a "strike"), that frame's score is the previous frame plus 10 plus the next two throws. (No second throw is taken). If all 10 pins are knocked down after a frame's second throw (a "spare"), that frame's score is the previous frame plus 10 plus the next throw. In the 10th frame, if the bowler's first throw is a strike, or the first two throws yields a spare, the bowler gets a third throw. The 10th frame's score is the previous frame's score plus the pins knocked down in the 10th frame's two or three throws. Given integers represents all throws for a game, output on one line each frame's score followed by a space (and end with a newline). Note that the number of throws may be as few as 11 (strikes in first 9 frames,…

Note that for this question, you can in addition use ``land'' for the symbol ∧ ``lor'' for the symbol ∨ ``lnot'' for the symbol ¬. Given the following three sentences:A) Every mathematician is married to an engineer.B) A bachelor is not married to anyone.C) If George is a mathematician, then he is not a bachelor. a) Convert A,B,C into three FOL sentences, whereMn(x): x is a mathematician.Er(x): x is an engineer.Md(x,y): x is married to y.Br(x): x is a bachelor.george: George is a constant. b) Show that A does-not-entail C. (Hint: Consider defining an interpretation I such that I models A, but does-not-model C.)c) Show that {A,B} entails C. (Hint: For a given interpretation I, consider two difference cases, the case where Mn(george) is true, and the case Mn(george) is false. For both cases, argue that it is always that I models C).d) Convert A,B, lnot C into a set of clausal forms, number your clauses. (Note that C is negated here!) e) Derive the empty clause from the set of clauses…

Correct code answer with output screenshot. Else downvoted. William is facilitating a get-together for n of his broker companions. They began a conversation on different monetary forms they exchange, however there's an issue: not all of his dealer companions like each cash. They like a few monetary standards, yet not others. For each William's companion I it is known whether he enjoys money j. There are m monetary standards altogether. It is likewise realized that a merchant dislike more than p monetary forms. Since companions need to have some normal subject for conversations they need to track down the biggest via cardinality (perhaps vacant) subset of monetary standards, with the end goal that there are essentially ⌈n2⌉ companions (gathered together) who like every money in this subset. Input The primary line contains three integers n,m and p (1≤n≤2⋅105,1≤p≤m≤60,1≤p≤15), which is the number of broker companions, the number of monetary forms, the greatest number of…
