may I ask you how to differ "to be+able+to+verb" and "enable"?
It is not about making differences, it is about conciseness.
A part of writing material I found on internet that may guide you.It is always better you say whatever you want to say without using any more words that necessary. Reader would begin to skim rather than peruse, confident that he could skip clauses or even whole sentences without missing anything important. In short, wordiness trains the reader to disengage with the material he is reading. This called conciseness. Conciseness also dictates that certain wordy phrases always be avoided.
Some examples:I was stunned by the fact that the politician would lie so brazenly
I was stunned by the politician brazen liesThe reason why people go to Jakarta is because it is to find better life.
Better life affects a substantial migration to Jakarta.
Could you see the differences?
Needless to say, I suggested you change "are still able"
in practising conciseness.
Actually I've rewritten this essay, and for the first I said about the improvement of medical care that caused longer life expectancy, but it was off topic because the task asked about "development"? so i restate about the development of this trend which people have more life expectancy. Can you give me suggestion of this?
If I am in line, the prompt says that the one of the consequences of improved medical care increase people live expectancy or they may live longer. Why I say that probably you are little bit out of topic is because there is no explanation about the medical care improvement
. If I were you, in purpose to break the prompt down, I would compare the medical care in the past and it's to date development
that might bring the advantages of increasing people's life expectancy. Perhaps you can say, in the era that baby incubator is have not invented yet there are different numbers of baby death toll compared to nowadays, or the invention of HIV vaccine temporary could delay the gradual decrease of antibody system of people who infected HIV.
Hopefully this helps :D
