Difficulty: HardOccupational and Specialized Registers

Match each specialized occupational term on the left with its precise technical definition or professional application on the right.

  • ProphylaxisA measure or treatment designed and administered specifically to prevent disease rather than cure it.
  • Amicus curiaeAn impartial adviser, not party to a lawsuit, who voluntarily offers information on a point of law or relevant legal expertise.
  • ArbitrageThe simultaneous buying and selling of assets in different markets to exploit price discrepancies for risk-free profit.
  • Dead reckoningThe navigation technique of estimating current position based on a previously known point, elapsed time, speed, and course.

Answer

Prophylaxis matches the medical prevention of disease; Amicus curiae matches an impartial legal adviser to the court; Arbitrage matches exploiting market price discrepancies for profit; Dead reckoning matches position estimation using speed, direction, and time.
Each pair correctly matches a technical term to its specific operational definition within its native domain: Prophylaxis to preventative medicine, Amicus curiae to non-party legal advisement, Arbitrage to cross-market financial trading, and Dead reckoning to navigation estimation.

Step-by-Step Solution

1
Analyze the specialized domain of each term on the left.
Prophylaxis originates from medical/clinical register; Amicus curiae from legal register; Arbitrage from financial/trading register; Dead reckoning from aviation/nautical navigation register.
Identifying the target professional field isolates the context needed for accurate mapping.
2
Pair each term with its exact technical meaning.
Prophylaxis corresponds to disease prevention; Amicus curiae corresponds to an impartial friend of the court; Arbitrage corresponds to cross-market price exploitation; Dead reckoning corresponds to relative position calculation.
Distinguishing precise specialized vocabulary prevents confusion with general dictionary meanings or related occupational terms.
