An industrial systems engineer is writing a program to monitor the thermal safety of a chemical reactor. Consider the following pseudocode subroutines:

function MonitorSafety(t_curr, t_set, multiplier)
    offset = t_curr - t_set
    print(EvaluateRisk(offset, multiplier))
endfunction

function EvaluateRisk(diff, mult)
    score = (diff * mult) - 5
    if score > 15 then
        score = score + GetFactor(mult)
    endif
    return score
endfunction

function GetFactor(val)
    if val > 6 then
        return 8
    else
        return 4
    endif
endfunction
