Correct: C. 2.43m

The net height in men's volleyball is 2.43 meters (7 feet 11 5/8 inches), while in women's volleyball it is 2.24 meters (7 feet 4 1/8 inches). The net is 9.5 meters wide and 1 meter deep, with antenna extensions that mark the crossing boundaries. Net height in beach volleyball is slightly lower to account for sand's effect on jumping ability.

Correct: C. 1.524 metres

The net in badminton is 1.55 metres high at the posts and 1.524 metres at the centre of the court. The slight sag at the centre is a deliberate design feature. The net is 6.1 metres wide covering the full width of the doubles court.

Correct: C. The non-volley zone - the 7-foot area on each side of the net where volleys are prohibited

The kitchen in pickleball refers to the non-volley zone - a 7-foot area on each side of the net where players cannot volley the ball (hit it out of the air). Players may enter the kitchen to play a ball that has bounced in it. The kitchen rule prevents players from standing at the net and smashing easy volleys.

Correct: B. The metal strip at the bottom of the front wall below which shots are out

The tin in squash is the metal strip at the bottom of the front wall that extends the full width of the court. Any shot that strikes the tin is immediately out and the point is awarded to the opponent. The tin is 48 cm high in standard squash and 43 cm in hardball squash.

Correct: D. A specialised defensive player wearing a different coloured jersey who cannot attack above net height

The libero is a specialised defensive back-row player in volleyball who wears a distinctively coloured jersey. The libero cannot serve (in some competitions), attack above the height of the net, or play in the front row. They can replace any back-row player without using a substitution.

Correct: C. Point-a-rally scoring to 11 with a let system

Modern professional squash uses point-a-rally scoring (PAR) to 11 points where a point is scored on every rally regardless of who served. A player must win by 2 clear points. If the score reaches 10-10 play continues until one player leads by 2. Games are played best of five.

Correct: C. A point replayed due to interference between players

A let in squash is when a point is replayed without a winner because one player was interfered with by their opponent and prevented from making a winning shot. When a let is called the rally is replayed from the serve. A stroke (direct point award) is given when the interference prevented a winning shot.

Correct: B. Racquetball uses a hollow rubber ball on a fully enclosed court with a back wall while squash uses a softer ball and different court dimensions

Racquetball is played in a fully enclosed court (including a back wall and ceiling that are in play) using a hollow rubber ball and a short-handled racquet. Squash uses a smaller court with specific out lines on the walls and a softer bouncy ball. The two sports share the enclosed court concept but have significan'tly different dynamics.

Correct: A. A kill shot is an attacking spike aimed steeply into the court while a passing shot goes parallel to the net

In volleyball a kill is a successful spike that immediately ends the rally by landing in the opponent's court or forcing an unretrieval dig. A passing shot typically refers to a controlled ball-handling technique to set up the next play rather than an attacking shot. Kill percentage (kills per attack attempt) is a key statistic for measuring hitter efficiency.

Correct: A. A serve where the ball is struck at an angle to create topspin, backspin, or sidespin

A spin serve in table tennis involves striking the ball at specific angles to impart topspin, backspin, or sidespin. The spin dramatically affects how the ball bounces off the table and how the opponent's paddle interacts with it upon return. Mastering spin serves and reading opponents' spin is fundamental to elite table tennis.

Correct: D. A forehand stroke where the paddle is brushed upward creating forward rotation on the ball

A topspin stroke in table tennis is executed by brushing the paddle upward on the ball creating forward spin (topspin) that causes the ball to dip sharply when it reaches the opponent. Topspin is the primary offensive stroke in modern table tennis and when played with extreme power is called a loop.

Correct: A. The T-junction of the mid-court lines - controlling it gives optimal court positioning

The T is the T-shaped junction of the service box lines at the centre of the squash court. Controlling the T (returning to it after each shot) is the fundamental tactical principle of squash - it provides the best position to reach any area of the court equally quickly and forces the opponent to play shots away from it.

Correct: B. Feather shuttles use real goose feathers and fly more accurately while synthetic shuttles are cheaper and more durable

Feather shuttlecocks use real goose or duck feathers (typically 16 per shuttle) attached to a cork base and are used in professional competition because of their superior flight characteristics.

Correct: C. The back wall is in play and balls can be retrieved off it allowing players to play defensive shots that bounce off the back wall

The back wall in squash is a live surface - balls that reach it can be retrieved and returned to the front wall. The back wall allows players to play defensive shots from very deep positions turning seemingly unwinnable situations into retrieved rallies. Skilled players use the back wall angle to extract themselves from pressure.

Correct: C. A shot hit diagonally from one side of the front wall to the opposite corner of the back of the court

A crosscourt shot in squash travels diagonally from one side of the court to the other - typically from one front corner to the opposite back corner or diagonally across the middle. Crosscourt drives are used to move an opponent away from the T position and are fundamental to rally construction.

Correct: C. The BWF World Championships held biennially organised by the Badminton World Federation

Correct: C. A quick low serve used in doubles that travels flat and fast

A flick serve in badminton is used in doubles play - it appears identical to a low short serve but at the last moment the wrist is used to generate extra power and speed pushing the shuttle high over the opponent who is positioned to intercept a low serve. It is a deceptive serve targeting the back of the service box.
