Complete the following sentence

Complete the following sentence with a (compound) word derived from the one(s) given in bracket.

With a little more effort, what seemed（ ）failure may turn to glorious success. (hope)

本题考查常见名词的形容词形式。
由系动词seem和名词failure可知，空缺处应填形容词进行修饰，hope作名词意为“希望”，其形容词形式有“hopeful给人以希望的”和“hopeless无望的”，此处修饰“failure失败”，应使用hopeless。
句意：再多一点努力，看似无望的失败可能就会变成辉煌的成功。
