   In an RPG, a potion that should restore 50 HP sometimes restores 100 HP when the character is at exactly 1 HP. The code uses a formula that adds a bonus when HP is below 10%. What is the most likely cause?

   • AAn unintended interaction between the potion and the character's level, causing a double effect.
   • BA design flaw in the potion's intended effect, where the bonus is actually meant to be applied always.
   • CA boundary issue in the percentage calculation, where the condition 'below 10%' is incorrectly evaluated at exactly 1 HP.
   • DA logic error in the potion's effect, where the bonus is applied unconditionally.

   In a simulation game, a building's production rate doubles when the game speed is set to 'fast' instead of increasing proportionally. The code uses a time delta to scale production. What is the most likely cause?

   • AA boundary issue in the game speed setting, where the 'fast' option triggers a different code path.
   • BA design flaw in the production system, where the intended rate is actually double at fast speed.
   • CAn unintended interaction between the production system and the game's frame rate, causing a boost.
   • DA logic error in the time delta calculation, where the production rate is multiplied by the wrong factor.

   A game's crafting system allows players to combine two items to create a new item, but the resulting item has the wrong stats. The design document specifies the correct stats. What is the most likely root cause of this defect?

   • AAn implementation error in the crafting logic.
   • BA design flaw in the crafting recipe.
   • CA requirement misunderstanding by the developer.
   • DAn unintended interaction with another game system.

   In a strategy game, a unit's movement speed is sometimes doubled when the unit is selected and the player holds the shift key to queue commands. The unit's speed is supposed to be constant. The code has a modifier system for speed. What is the most likely cause?

   • AAn unintended interaction between the shift-key command queue and the speed modifier system, causing a speed boost.
   • BA boundary issue in the speed calculation, where the speed is doubled at a certain threshold.
   • CA design flaw in the speed system, where the intended speed is actually double when shift is held.
   • DA logic error in the movement code, where the speed is set to double when a command is queued.
