# This is not a simple problem !
# The solution requires a more elaborated analysis and
# a use of the English dictionary
# So you can skip the problem without losing anything
# But here are some ideas on how to start:

    for f in float_list:
        if abs(f-x) < min_distance:
            closest = f
            min_distance = abs(f-x)
    return closest
