Spoiler for Thank you, a little more, please

I gather there is an observer who is looking at the row, and sees it from Observer's Left to Right. And, from what you said, the person on Observer's far left is wearing Red.

(1) When you say that "Chi has two facing backward on his right", does "backward" mean "facing away from the observer", or does it mean, "facing the opposite of Chi"?Chi's "his left/right" refer to Chi orientation

Spoiler for

(2) In the same case, does "on his right" mean "to the same side of the line as Chi's right hand" , or does it mean "to the same side of the line as Observer's right hand" [ I assume it means Chi's right hand ) or right side

(3) Do the captives know that the person on Observer's far left is wearing Red?   Yes, like reading, left to right :ROYGBVW

Spoiler for Perhaps

The hostage from China says he is wearing green? Not him.

Spoiler for Last question, I am sure

You said a people to a hostage's left/right are in a hostage's orientation. Is it also true that "facing forward/backward" is in the hostage's orientation?

Thank you in advance.  Nice tough problem!

Yes captainEd, sorry for that, I should have use "her" for all hostages (beauty pageant  contestants) to differ from observer  

Thank you in advance.  Nice tough problem!

Seven International Hostages are lined up in a row .Some are standing or sitting ,

facing backward or forward.All were blindfolded with different colored duct tapes 

and ordered not to move. None has any information about the other hostages.

 

The terrorist leader announced to the nationals before him on the speakers that.. 

they shall all be released if they all can guess  their blindfold's color correctly 

which are  in the order as ff :  Red  Orange Yellow  Green  Blue  Violet   White 

                                            

Chi   has  2 hostages facing backward on his right, 3 sitting down on his right. 

Jap  has  2 hostages facing forward on his left, 3 standing up on his left                     

Fra   has  1 hostage facing backward on his right, 3 standing up on his left.                                           

Rus  has  3 hostages facing backward on his left, 2 sitting down on his left.                        

Eng  has  2 hostages facing forward on his right, 3 sitting down on his right.                      

Ger  has  2 hostages  facing forward on his left, 1 standing up on his right.                  

Spa  has  2 hostages facing backward on his left, 2 standing up on his left

 

In 60 seconds 1 hostage should raise both his  tied hands then will be pulled

behind the row and  will be shot in the head right on the spot in case he fails

to shout the correct color of his blindfold .The other  nationals  will share the 

same fate. If he is right, all the others should not fail or else everyone is going 

to die. If none of them will guess in a minute all will remain hostages..

 

Who would first raise his hands? 

 

The two possible arrangements are

Spoiler for

Jap, Chi, Rus, Spa, Ger, Fra, Eng

Eng, Fra, Ger, Spa, Rus, Chi, Jap

Since the hats are displayed in the following order

Red  Orange Yellow  Green  Blue  Violet   White

If 'getting pulled behind the row' (see colored part above) means being pulled backwards in the prisoner's orientation, then the prospect of survival for all the prisoners is 1/2. Anyone besides Spa can raise his hand and guess one of his two possible color. For instance, Jap is either Red (beginning of the line) or White (last in line). If his guess is correct, everyone else should be able to guess their color. If his guess is *incorrect*, then everyone else should also be able to guess their color, although it might not do them much good at that point according to the OP.

If 'getting pulled behind the row' means getting pulled behind the row from an observer's perspective, then the prisoners can use that information to improve their survival odds. In that case, Spa should call Green. Once he is pulled 'behind' the row, the other prisoners would know which of the two arrangements they are in.

Spoiler for well..

done!

The front and back of the row is of announcer's reference

Relative positions/directions of the hostages

> Eng >

< Fra <

< Ger <

< Spa <         

> Rus >

< Chi <

> Jap >

All the nationals know this. And BUSHINDO know this.

They are just waiting for Spa shout Green to obtain the reference.
