“It was an interesting day.”—President Bush, recalling 9/11 
This is enticement for you to spread the hoax.
some times I confuse in detect the topic in opinion essay, for example in this question:
(Due to the development and rapid expansion of supermarkets in some countries, many small, local business are unable to compete. Some people think that the closure of local business will bring about the death of local communities.). I have confused if the topic is (inability of local business to compete) and other information is supporting or it is (closure of local business will bring about the death of local communities) , so how can I identify the main topic in such question ?
Thanks a bundle
There are many different versions, most of which share key phrases.
I am assuming the reason you use past perfect tense throughout the whole essay is because the topic is in past perfect tense. But even for the topic, I don’t understand why this tense is being used instead of just present tense to describe the phenomenon in general, instead of implying the impact of SNS has ended? It is still happening, right?
