Many inventions, such as paper, cars and computers, are undoubtedly useful. (1), for me, the most useful invention is the Rubik's Cube, invented by Ernő Rubik. (2), it trains my brain and improves my thinking skills. When I turn its colourful sides, I learn to solve problems step by step. (3), it teaches me patience and helps me stay focused. Without it, I might give up on difficult tasks too easily. (4), I believe the Rubik's Cube is the most useful invention.

答案
(1) However
(2) To start with
(3) What's more
(4) Therefore
(2) To start with
(3) What's more
(4) Therefore
解析
(1) 根据句意，前面提到许多发明无疑是有用的，然而对于我来说，最有用的发明是魔方，所以应选表示转折的连接词。
(2) “it trains my brain and improves my thinking skills”是魔方的第一个优点，“To start with”表示首先，符合语境。
(3) “it teaches me patience and helps me stay focused”是魔方的另一个优点，与前文是递进关系，“What's more”表示而且，进一步说明魔方的优点。
(4) “I believe the Rubik's Cube is the most useful invention”是结论，“Therefore”表示因此，用于引出结论。
(5) 题目要求有一个连接词多余，“On the other hand”一般用于两者对比，此处不适用；“However”在(1)处已正确使用表达转折，其他多余词不考虑。
