Answer: D. to inform readers about Blair's apology
Explanation:
The article excerpt provides information about Blair's apology in an unbiased way, meaning that it doesn´t intend to convince the reader of whether an apology was in order or not. 
Option A is incorrect because the idea that British diplomats had allegedly been working non-stop is how Blair, and not the article, intends to persuade people not to blame them. Option B is incorrect because the article doesn´t ask or even hint for people to help British survivors. Option C is incorrect because the article is not meant to explain why Britons were deserted, but to inform how Blair considers they were not deserted at all.

Letter to the District Chief Executive about three problem in my locality.

To, 
The District Chief Executive
....................
3 May 2016
Subject: Problems faced by residents of ABC Apartment complex.
Dear Sir,
It is with a deep concern for the welfare of the community that I am writing to you about several issues that are presently affecting our locality.
First are the damaged roads and street lights, which leave the roads dark and dangerous at night. There have been numerous accidents that were at times too extreme.
Secondly, there's the issue of water shortage which has left many of the residents unable to even prepare their meals on time. Some are even left to cook their meals with bottled water from the shops, which is expensive.
And thirdly, I would also like to point out the issue of the garbage collection system. Recently, the collectors have stopped coming to our locality, leaving residents unable to dispose of their wastes and stinking the whole area. This has also led to an increase in mosquitoes which is dangerous for us all.
I hope this letter gets your attention. We are looking forward to any response or solution from the concerned authorities.
Thank you.
Regards,
Mr. Ashish Sharma

Answer and Explanation:
We can tell from the tone of this writer that he/she really appreciates letter writing, as opposed to typing. Essentially, it's saying that when you handwrite something, there's an intimate component to it that makes the piece of literary work feel totally your own. This is opposed to the mechanical feel of typing, where everything is one font and you're simply clacking out the letters. Instead, with letter handwriting, you're slower at it (because handwriting something is quite slow), which allows you to enjoy your writing a little more and "smell the proverbial roses" by including little details here and there that truly make the piece a very self-connected one.
Hope this helps!
