Answer :
The most direct and clear option is E. "I want to go to the arcade to play games and have fun".
To make a sentence more concise and remove extra words, one can eliminate unnecessary adverbs, and streamline phrases that imply the same meaning. Here, the word 'just' is redundant since the desire to go to the arcade is already clearly stated without it.
Additionally, the phrase 'in order to' is unnecessary because using 'and' is sufficient to link the actions of playing games and having fun, which are the main reasons for going to the arcade.
Using examples, sentence 2 can be made shorter by removing 'have to', leaving 'To succeed, work hard.' Sentences 3 through 8 demonstrate how you can modify sentences to focus on the key message by removing or replacing words that aren't essential. This practice not only creates sentences that are easier to read but also makes the text more impactful.
