Neutral yes-no questions focus the entire clause/event. In Russian,
such questions consist of a fronted finite verb followed by the
interrogative complementizer li, as in (6).

The annotated c-structure corresponding to (6) is shown in
(7). In particular, the finite verb in I 
is annotated ( 
Q-FOC)= 
, similar to the annotation used with focused maximal
projections in this construction in (4) and (5). As seen in
the corresponding f-structure in (8), this correctly places the
entire f-structure in Q-FOC, which corresponds to focusing the entire
event.

However, there is a problem in that although the entire event is contained in the Q-FOC, a circularity is created in that the Q-FOC contains itself.
