It’s definitely either a or d, my guess would be d
Online learning has heavily affected students, due to the limited communication, meaning not all the students reach their full understanding of the subject. There are many negative effects to it, such as; the lack of efficiency of technology, the difficulty for pupils to understand the concepts taught, and online learning causes social isolation and results in pupils not developing the necessary communication skills.
B is incorrect. The answer is D the topic.
Answer:
Topic sentences are followed by supporting details.
Explanation:
When writing a report, the student can adopt different organizational structures that match more with the text he will write. However, one of the most efficient structures for writing a report is the use of topical phrases followed by supporting details.
This structure is efficient, because it allows the author to establish an argument or an essential statement for the report, with several supporting phrases that prove that the statement or argument is true, in addition to enriching the text and showing that the author has researched and prepared to write it.
For this I would choose the first choice, A. "Eileen bought pants but not a new jacket."
A complex sentence is formed by an independent and a dependent clause. An independent clause is a part of a sentence that can still be a sentence on it's own. For example, "Eileen bought pants." could be a valid sentence.
A dependent clause is the opposite, and is a part of a sentence that can not still be a sentence on it's own. "But not a new jacket." is not a valid sentence.
I hope this was helpful.
