Make sure that your grammar makes the correct predictions for the sentence below:
(2) Ingrid buys olives <br>
(3) *Ingrid tried buys olives
-->
In this unit, we will extend the grammar to license sentences with verbs like 'try' and 'seems' which have interesting properties.
==''try (Control verb)''==
Notation:
In the exercises of this unit, we will have to implement '''Control''': this means that a GF of the higher verb and the SUBJ of the higher verb's XCOMP are identical.
In XLFG, this is written as follows:
* (↑SUBJ) = (↑XCOMP SUBJ);  means: the SUBJ of the higher verb and the XCOMP's SUBJ are identical.
* (↑OBJ) = (↑XCOMP SUBJ);  means: the OBJ of the higher verb and the XCOMP's SUBJ are identical.

Implement the following grammatical assumptions:
* 'to' (the infinitive marker): assume that it is marked [IM:+].
* 'buy': [VFORM:INF]
Make sure that your grammar makes the correct predictions for the sentences below:
(2) Ingrid buys olives <br>
(3) *Ingrid tried buys olives
==''seem(Raising verb)''==
Notation:
The verb ''seem'' differes from the verb ''try'' in that ''seem'' does not assign a semantic role to its SUBJ. This is the first time we encounter such verbs. In XLFG, GFs that the predicate does not assign a role to are written between the closing > and the final apostrophe, as follows:
* PRED:'X<...>Y'
Meaning of the line above: the GFs listed in ... are assigned semantic roles by the predicate, but the grammatical function Y is not.

Extended Coherence Condition [non-final version] (p. 138)
* All governable functions present in an f-structure must occur in the value of a local PRED feature.
* All functions that have a PRED value must have a theta role.
