Question 868710
<pre>
Here are the spaces:

___  ___  ___  ___  ___  ___ 
 1    2    3    4    5    6  
</pre>
>>...person D stands in space six with no one beside him...<<
<pre>
So we have this, with 0 indicating the empty space

___  ___  ___  ___  _0_  _D_ 
 1    2    3    4    5    6    

So all the other spaces 1 through 4 are filled.
</pre>
>>...Person E is the third person from the left...<<
<pre>
So we have

___  ___  _E_  ___  _0_  _D_ 
 1    2    3    4    5    6 
</pre>
>>...Person A is to person B's immediate left...<< 
<pre>
The only two adjacent spaces remaining are spaces 1 and 2,
so we have

_A_  _B_  _E_  ___  _0_  _D_ 
 1    2    3    4    5    6
</pre>
>>...where is person C?...<<
<pre>
C is in the only remaining space, 4:

_A_  _B_  _E_  _C_  _0_  _D_ 
 1    2    3    4    5    6
