Photograph That Shook The World.

Thousands online have shared an image of a Syrian child with her hands raised in surrender - but what is the story behind it?
Those sharing it were moved by the fear in the child's eyes, as she seems to staring into the barrel of a gun. It wasn't a gun, of course, but a camera, and the moment was captured for all to see. But who took the picture and what is the story behind it? BBC Trending have tracked down the original photographer - Osman Sağırlı - and asked him how the image came to be.
It began to go viral Tuesday last week, when it was tweeted by Nadia Abu Shaban, a photojournalist based in Gaza. The image quickly spread across the social network. "I'm actually weeping", "unbelievably sad", and "humanity failed", the comments read. The original post has been retweeted more than 11,000 times. On Friday the image was shared on Reddit, prompting another outpouring of emotion. It's received more than 5,000 upvotes, and 1,600 comments.
Accusations that the photo was fake, or staged, soon followed on both networks. Many on Twitter asked who had taken the photo, and why it had been posted without credit. Abu Shaban confirmed she had not taken the photo herself, but could not explain who had. On Imgur, an image sharing website, one user traced the photograph back to a newspaper clipping, claiming it was real, but taken "around 2012", and that the child was actually a boy. The post also named a Turkish photojournalist, Osman Sağırlı, as the man who took the picture.
BBC Trending spoke to Sağırlı - now working in Tanzania - to confirm the origins of the picture. The child is in fact not a boy, but a four-year-old girl, Hudea. The image was taken at the Atmeh refugee camp in Syria, in December last year. She travelled to the camp - around 10 km from the Turkish border - with her mother and two siblings. It is some 150 km from their home in Hama.
"I was using a telephoto lens, and she thought it was a weapon," says Sağırlı. "İ realised she was terrified after I took it, and looked at the picture, because she bit her lips and raised her hands. Normally kids run away, hide their faces or smile when they see a camera." He says he finds pictures of children in the camps particularly revealing. "You know there are displaced people in the camps. It makes more sense to see what they have suffered not through adults, but through children. It is the children who reflect the feelings with their innocence."
The image was first published in the Türkiye newspaper in January, where Sağırlı has worked for 25 years, covering war and natural disasters outside the country. It was widely shared by Turkish speaking social media users at the time. But it took a few months before it went viral in the English-speaking world, finding an audience in the West over the last week.

GRE sample question.

In a game, exactly six inverted cups stand side by side in a straight line, and each has exactly one ball hidden under it. The cups are numbered consecutively 1 through 6. Each of the balls is painted a single solid color. The colors of the balls are green, magenta, orange, purpose, red and yellow. The balls have been hidden under the cups in a manner that conforms to the following conditions:

The purple ball must be hidden under a lower-numbered cup than the orange ball.
The red ball must be hidden under a cup immediately adjacent to the cup under which the magenta ball is hidden.
The green ball must be hidden under cup 5.




1.Which of the following could be the colors of the balls under the cups, in order from 1 through 6?
(A) Green, yellow, magenta, red, purple, orange
(B) Magenta, green, purple, red, orange ,yellow
(C) Magenta, red, purple, yellow, green, orange
(D) Orange, yellow, red, magenta, green, purple
(E) Red, purple, magenta, yellow, green, orange
Ans : C
Explanation:  
Inverted cups are numbered 1 through 6 consecutively. Six balls of different colors are hidden under them. The colors are G, M, O, P, R, Y using the first alphabet of each color. We use the letter B for ball. For example PB stands for purple colored ball.
The given conditions are
(i) PB < OB ('<' indicates that this purple ball is hidden in a lower numbered cup than orange ball)
(ii) RB, MB are adjacent .
(iii) GB = 5 (this means that the green ball is hidden under cup No. 5)
No restrictions given for yellow colored ball.

(A) Wrong. Green Ball is not under Cup 5.
(B) Wrong. Green Ball is not under Cup 5.
(C) Correct: All three above conditions satisfied.
(D) Wrong : Purple Ball is not before orange Ball.
(E) Wrong : RB and MB are not adjacent.




2.If the magenta ball is under cup 4, the red ball must be under cup
(A) 1
(B) 2
(C) 3
(D) 5
(E) 6
Ans : C
Explanation: 
Inverted cups are numbered 1 through 6 consecutively. Six balls of different colors
are hidden under them. The colors are G, M, O, P, R, Y using the first alphabet of
each color. We use the letter B for ball. For example PB stands for purple colored
ball.
The given conditions are
(i) PB < OB
('<' indicates that this purple ball is hidden in a lower numbered cup than orange ball)
(ii) RB, MB are adjacent .
(iii) GB = 5
(this means that the green ball is hidden under cup No. 5)
No restrictions given for yellow colored ball.

Here MB = 4. Since GB = 5, RB which is to be adjacent to MB must occupy place 3.
So, C is the correct answer.



3. A ball of which of the following colors could be under cup 6?
(A) Green
(B) Magenta
(C) Purple
(D) Red
(E) Yellow
Ans : E
Explanation:
Inverted cups are numbered 1 through 6 consecutively. Six balls of different colors
are hidden under them. The colors are G, M, O, P, R, Y using the first alphabet of each color. We use the letter B for ball. For example PB stands for purple colored ball.
The given conditions are
(i) PB < OB
('<' indicates that this purple ball is hidden in a lower numbered cup than orange ball)
(ii) RB, MB are adjacent .
(iii) GB = 5
(this means that the green ball is hidden under cup No. 5)
No restrictions given for yellow colored ball.

(A) Wrong: GB is 5 and cannot be 6.
(B) Wrong: RB cannot be 5 and so MB, RB cannot be adjacent.
(C) Wrong: If PB = 6, there is no place for OB and so PB < OB fails.
(D) Wrong: If RB = 6, then MB cannot be 5 as GB = 6. So the condition RB, MB adjacent fails.
(E) Correct: No restriction for yellow Ball.

So, the answer is E. 



4. If the purple ball is under cup 4, the orange ball must be under cup
(A) 1
(B) 2
(C) 3
(D) 5
(E) 6
Ans : E
Explanation: 
Inverted cups are numbered 1 through 6 consecutively. Six balls of different colors
are hidden under them. The colors are G, M, O, P, R, Y using the first alphabet of
each color. We use the letter B for ball. For example PB stands for purple colored
ball.
The given conditions are
(i) PB < OB
('<' indicates that this purple ball is hidden in a lower numbered cup than orange ball)
(ii) RB, MB are adjacent .
(iii) GB = 5
(this means that the green ball is hidden under cup No. 5)
No restrictions given for yellow colored ball.

PB = 4
(A), (B), (C) are wrong as orange Ball should be after 4.
(D) is wrong because Green Ball should be at 5.
(E) is correct.

So the correct answer is E.



5. Which of the following must be true?
(A) The green ball is under a lower-numbered cup than the yellow ball.
(B) The orange ball is under a lower-numbered cup than the green ball.
(C) The purple ball is under a lower-numbered cup than the green ball.
(D) The purple ball is under a lower-numbered cup than the red ball.
(E) The red ball is under a lower-numbered cup than the yellow ball.

(ii) RB, MB are adjacent .
(iii) GB = 5
(this means that the green ball is hidden under cup No. 5)
No restrictions given for yellow colored ball.

(A) Wrong: It can happen as number 6 slot is vacant. But it is not a must.
(B) Wrong: Orange Ball can be event at Number 6.
(C) Correct: Purple Ball cannot be at Number 6 as it should be before Orange Ball as per the initial condition.
Since GB=5, PB must be less than Green Ball number.
(D) and (E) are also not a must.

So the correct answer is C.

Which direction is the bus going?

This is actually a brain teaser for kids... and many of them give correct answer to this... But it has been found that many adults were unable to give correct answer maybe their brain tend to "Over think" the problem instead of using common sense So, here is a image of a bus driving in road of city you live. Now tell me which direction is the bus going... Left or Right. And I give you a hint... answers may be different. Answer: Well, the direction may differ as according to city(country) you live. The place I live has a left side driving rule(i.e Drive from left side of road). So in my city the bus must be going left. Why left?? Which side the bus has it's door on? Did you get your answer?
