One step at a time

A visitor can enter by either route: reaching the required level or holding a pass. >= includes the exact level boundary; or accepts either true condition.

The browser checks a returned boolean for different visitors. This Learning simulation is not a running Roblox experience or a multiplayer security system.

Your task

Implement canEnter(playerLevel, requiredLevel, hasPass). Return a boolean: allow a visitor at or above the required level, or a visitor with a pass. Keep the final return canEnter so the checker can try the visible cases and additional boundaries. This is a Learning simulation, not a Roblox gate.

Interface: canEnter(playerLevel, requiredLevel, hasPass) -> boolean

Input	Expected
Level 4, requirement 5, no pass`4, 5, false`	`false`
Level 5, requirement 5, no pass`5, 5, false`	`true`
Level 7, requirement 5, no pass`7, 5, false`	`true`
Level 2, requirement 5, pass`2, 5, true`	`true`

local function canUseBench(hasReservation, isOpenDay)
    return hasReservation or isOpenDay
end
return canUseBench

A reservation and an open day are alternative routes. No reservation on an open day still permits use.

The rule is: a visitor reaches the required level OR has a pass. The level route includes equality, so it needs >=. The pass is another route, not an extra requirement.

or succeeds when either condition is true. and would require both. not reverses truthiness; not hasPass describes a visitor without a pass.

The gate picture is labeled Learning simulation. It reads the actual evaluated return value. It is not a Roblox server, and its access logic alone does not implement secure multiplayer permissions.

Try every visible case. The starter passes a visitor above the requirement but fails equal-level visitors and low-level visitors with a pass. Passing one example is not enough.
