Question: What chop matches the topspin of the opponent's shot with a backspin?
About the article "Table tennis", section "Chop".

Candidate passages:
A chop is the defensive, backspin counterpart to the offensive loop drive.
A chop is essentially a bigger, heavier push, taken well back from the table.
The racket face points primarily horizontally, perhaps a little bit upward, and the direction of the stroke is straight down.
The object of a defensive chop is to match the topspin of the opponent's shot with backspin.
A good chop will float nearly horizontally back to the table, in some cases having so much backspin that the ball actually "rises".
Such a chop can be "extremely" difficult to return due to its enormous amount of backspin.
Some defensive players can also impart no-spin or sidespin variations of the chop.
In ball sports, topspin is a property of a ball that rotates forwards as it is moving.
Topspin on a shot imparts a downward force that causes the ball to drop, due to its interaction with the air (see Magnus effect).
It can be generated by hitting the ball with an up-and-forward swing, with the racquet facing below the direction it is moving.
A topspin shot is the opposite of the slice; topspin itself is the opposite of backspin. 
In competitive table tennis, effective command of topspin is indispensable, not only in order to be able to execute an attack shot counter to a backspin ball, but also in order to be able to execute a speed shot when the ball is already lower than the net.
In table tennis the best defense for a top spin loop is a block close to the table which involves a firm fixation of the paddle and a slight movement forwards with an angle less than 90 degrees.
Another way of defending the topspin is to counterattack with a topspin or slice the ball. 
"David Crane's Amazing Tennis" simulates the men's singles game across three set matches, the game is viewed from behind the player.
Clay, grass and hard courts are available, and the player can specify handedness.
There are a selection of fictional computer controlled opponents available, each with different strengths, and a two player local multiplayer option is available.
Players can perform various shots, such as topspin, backspin, lob and drop shots. 
A flat shot in tennis is made by striking the ball at a neutral level.
Unlike the backspin and topspin the ball is hit with a swipe at neutral level.
This effect is created by driving through the ball to push it forward rather than brushing up or down the back creating spin.
The shot is commonly used for power and helps quicken the pace on the ball during play.

Question: What is FEL?
About the article "Electron", section "Other applications".

Candidate passages:
Fel is a commune in the Orne department in north-western France. 
It is common industry practice to divide front-end-loading activities into three stages: FEL-1, FEL-2, and FEL-3.
For each stage, typical deliverables are listed given below : 
Fel Legaspi is the incumbent, his opponent is Alfredo "Fred" De Guzman Germar. 
Fel d 1 is a protein that in cats is encoded by the "CH1" (chain 1/Fel d 1-A) and "CH2" (chain 2/Fel d 1-B) genes.
Fel d 1, produced largely in cat saliva and sebaceous glands, is the primary allergen present on cats and kittens.
The protein is of an unknown function to the animal but causes an IgG or IgE reaction in sensitive humans (either as an allergic or asthmatic response).
Removal of soft surfaces in the home (carpet, furniture), frequent washings of bed linens, HEPA filters and even washing cats has been proven to reduce the amounts of Fel d 1 present in the home.
Neutered males produce Fel d 1 in levels similar to females (both intact and spayed females produce Fel d 1 in similar levels).
Even though females and neutered males produce Fel d 1 in lower levels, they still produce enough to cause allergic symptoms in sensitive individuals.
