Example	Instruction stream (clickable)	Notes
(1) John is easy to please	[john, d, please, 'v_unerg', ['PRO', d0], 'Tinf', c, easy, v_be, 'T', c]	John (with unvalued uCase) is stacked after merge with please. v_unerg doesn't assign Case to John. Tinf assigns null Case to PRO. At the Local Extent (LE) boundary, the embedded CP, John (with unvalued uCase) is re-stacked. T picks up TOS John.
(2) The violin is easy to play the sonata on	[violin, the, on_nc, [sonata, the], play, 'v*', ['PRO', d0], 'Tinf', c, easy, v_be, 'T', c]	on_nc (no case) selects for the violin but does not assign it Case. At the Local Extent (LE) boundary, the embedded CP, the violin (with unvalued uCase) is re-stacked. Matrix T picks up TOS the violin.
(3) *What sonata is the violin easy to play on?	[violin, the, on_nc, [sonata, what:d], play, 'v*', ['PRO', d0], 'Tinf', c, easy, v_be, 'T', c_Q]	Does not converge. on_nc (no case) selects for the violin but does not assign it Case. what sonata is stacked (uScope). At the LE boundary, the embedded CP, what sonata (unvalued uScope) and the violin (unvalued uCase) are re-stacked. Matrix T fails to agree with TOS what sonata: nom Case clashes with acc Case assigned by embedded v*.
(4) The sonata is easy to play on this violin	[violin, this, on, [sonata, the], play, 'v_unerg', ['PRO', d0], 'Tinf', c, easy, v_be, 'T', c]	on assigns Case to this violin. v_unerg doesn't assign Case to the sonata. At the LE boundary, the embedded CP, the sonata (unvalued uCase) is restacked. Matrix T picks up TOS the sonata.
(5) What violin is the sonata easy to play on?	[violin, what:d, on, [sonata, the], play, v_unerg, ['PRO', d0], 'Tinf', c, easy, v_be, 'T', c_Q]	on assigns Case to this violin. v_unerg doesn't assign Case to the sonata. At the LE boundary, the embedded CP, the sonata (unvalued uCase) and what violin (unvalued uScope) are restacked. Matrix T picks up TOS the sonata. c_Q finds iWh what violin.
(6) Linguists are tough to please	[linguists, d, please, v_unerg, ['PRO', d0], 'Tinf', c, tough, v_be, 'T', c]	(Same as (1).) Linguists (with unvalued uCase) is stacked after merge with please. v_unerg doesn't assign Case to linguists. Tinf assigns null Case to PRO. At the LE boundary, the embedded CP, linguists (with unvalued uCase) is re-stacked. T picks up TOS linguists.
(7) It is tough to please linguists	[linguists, d, please,'v*', ['PRO', d0], 'Tinf', c, tough, v_be, it, 'T', c]	v* assigns Case to linguists. (No restacking is done at the LE boundary, the embedded CP.) Expletive it merge to the edge of v_be. Agree(matrix T,it) obtains.
(8) The book is easy to put on the table	[table, the, on, [book, the], put, v_unerg, ['PRO', d0], 'Tinf', c, easy, 'v_be', 'T', c]	(Same as (4).) on assigns Case to the table. v_unerg doesn't assign Case to the book. At the LE boundary, the embedded CP, the book (unvalued uCase) is restacked. Matrix T picks up TOS the book.
(9) What table is the book easy to put on?	[table, what:d, on, [book, the], put, v_unerg, ['PRO', d0], 'Tinf', c, easy, 'v_be', 'T', c_Q]	(Same as (5).) on assigns Case to what table. v_unerg doesn't assign Case to the book. At the LE boundary, the embedded CP, the book (unvalued uCase) and what table (unvalued uScope) are restacked. Matrix T picks up TOS the book. c_Q finds iWh what table.
