PTE Reading – Re-Order Paragraph explained!
First, you need to find the independent /starting sentence, which is the sentence that doesn’t refer to other sentences such as events, people or time et cetera.
With that being said, let’s look at which sentence(s) (can be more than one independent sentence) can or can’t be considered as independent /starting sentence.
B contains “this period” (what is this period?) and D contains “The war” (what war?), both sentences are dependent on something. Hence, neither can be used for the starting /independent sentence.
Now we are left with A and C, and the tricky part is that both sentence are candidate for the independent sentence, but we can only have one starting sentence.
So to figure out which one is the first sentence for this paragraph, we could find some clues by looking at the context of this question, which is about a series of events from 1920s to World Wall II(1939-1945). In most cases we can assume that the paragraph follows a chronological order by eliminating A as it refers to “By the beginning of Word War II”, whereas C refers to an earlier time of “1920s”. Hence starting/independent sentence is C.
Rest are pretty simple and straightforward. After C is B, this is because B contains “this period” which refers to “1920s-1930s” of C.
So C B
After B is A, as A is the other independent /starting sentence.
So C B A
Finally, we have D, not only because it’s the only sentence left, but also because D contains “The war” that is the reference of “World War II” mentioned in A.
Final Answer is C B A D
Good luck with your PTE preparation.
