Kept 'twice'? She did break it twice in three days, and it is the best number in the sentence, but the five has to say what the record was before it says how often it fell. Kept 'four', 'half' or 'seconds'? The times are why it is a record at all, and 'record' is already in the answer. Kept 'Cube' on its own? It is joined to Rubik's here, so the whole name is one word.
This one really happened. Lian Yunzhi is six, she is from Chengdu, and at home they call her Zhizhi. Over three days this month she twice broke the girls' world average for the three by three, first at a World Cube Association competition in Wuhan with an average of 4.52 seconds across five solves, then at Guangzhou with 4.27, which made her the first female speedcuber to average under four and a half seconds. She has learned more than thirteen hundred solving algorithms, practising two or three hours a day for the past year. In the video state television ran on Monday she is wearing a red gingham bow, and when the cube comes good she puts it down on the table, claps once and pumps her fist.
Every word, accounted for
AA little word. It only holds the sentence together.

brokeWhat she did to it. Not matched, not equalled.
theA little word. It only holds the sentence together.
girlsWhich record fell. Leave it out and the five says she beat everybody, and that is not what happened.
Rubik's-CubeJoined here so the whole name counts as one word, the way six-year-old does. On its own, Rubik's goes vague.
recordThe thing that fell, twice.
twiceThe strongest word here that is not in the answer. It says how often, and the five has to say what first.

threeHow long it took her to do it again. A number for the telling.
