Context: Death from laughter is a rare form of death, usually resulting from cardiac arrest or asphyxiation, caused by a fit of laughter. Instances of death by laughter have been recorded from the times of ancient Greece to the modern day.
 Question: can you have a heart attack from laughing Context: On December 4, 2012, the University of Arkansas named Bret Bielema the football team's new head coach. The position was previously held by John L. Smith, who served as the interim coach while UofA found a replacement for Bobby Petrino after Petrino was released from his duties with cause on April 10, 2012. Petrino followed the ten season tenure of Houston Nutt. The team plays its home games either at Donald W. Reynolds Razorback Stadium, located on the University of Arkansas campus in Fayetteville, or at War Memorial Stadium, located in Little Rock. In 1964, the Razorbacks were the only team to go through the regular season and a bowl game undefeated, and they were awarded the Football Writers Association of America National Championship. The 1969 team, led by quarterback Bill Montgomery, challenged the Texas Longhorns for a national championship in the Game of the Century.
 Question: have the arkansas razorbacks ever won a national championship in football Context: In gridiron football, the utility player is often capable of playing multiple positions, and often they may play both offense and defense. The concept was far more common in the early days of football, when pro teams used their best athletes as many ways as possible, and substitutions were far more restricted, meaning players had to stay on the field for offense, defense and ``special teams''. This was known as the one-platoon system.
 Question: can you play 2 positions in the nfl Context: The compound hydrogen chloride has the chemical formula HCl and as such is a hydrogen halide. At room temperature, it is a colorless gas, which forms white fumes of hydrochloric acid upon contact with atmospheric water vapor. Hydrogen chloride gas and hydrochloric acid are important in technology and industry. Hydrochloric acid, the aqueous solution of hydrogen chloride, is also commonly given the formula HCl.
 Question: would hydrogen chloride be a gas at room temperature Context: A partially ordered set is a bounded lattice if and only if every finite set of elements (including the empty set) has a join and a meet. For every element x of a poset it is trivially true (it is a vacuous truth) that ∀ a ∈ ∅ : x ≤ a (\displaystyle \forall a\in \varnothing :x\leq a) and ∀ a ∈ ∅ : a ≤ x (\displaystyle \forall a\in \varnothing :a\leq x) , and therefore every element of a poset is both an upper bound and a lower bound of the empty set. This implies that the join of an empty set is the least element ⋁ ∅ = 0 (\displaystyle \bigvee \varnothing =0) , and the meet of the empty set is the greatest element ⋀ ∅ = 1 (\displaystyle \bigwedge \varnothing =1) . This is consistent with the associativity and commutativity of meet and join: the join of a union of finite sets is equal to the join of the joins of the sets, and dually, the meet of a union of finite sets is equal to the meet of the meets of the sets, i.e., for finite subsets A and B of a poset L,
