Final answer:
The best way to revise sentences 11 and 12 with a coordinating conjunction is option 'd,' as it introduces a contrasting idea between having read the article and still desiring to annoy the sister.
Step-by-step explanation:
To revise sentences 11 and 12 using a coordinating conjunction, the best choice is the option that introduces a contrast between what is expected based on the previous action and what actually is desired despite that action.
In this context, the correct answer is 'd. I had actually read the article myself, but I still wanted to annoy her.' This revision effectively communicates the contrast between reading the article and still wanting to engage in the act of annoying the sister.
The best way to revise sentences 11 and 12 using a coordinating conjunction is option b.
In sentence 11, adding the coordinating conjunction 'and' creates a logical connection between the fact that the speaker had read the article and their desire to annoy their sister. It shows that both statements are true.
So, the revised sentences would be: 'I had actually read the article myself, and I still wanted to annoy her.'
