Homework 3 (due 18.07.2016)

Extend the abstract grammar 'Foods' on Slide 148 by adding the type 'Judgement'
and the functions 'PresPred', 'PastPred', 'PresNegPred', 'PastNegPred' of type 
'Comment -> Judgement'. The idea is to allow for comments in present and past
tense as well as for their negated versions:

those pizzas are expensive
this cheese was fresh
this fish isn't expensive
that boring cheese wasn't delicious

Modify the concrete grammar 'FoodsEng' on Slide 248 accordingly. Hint:
Linearize 'Pred' by 'mkCl', have a look at Slide 266, and search for
"Tense" and "Polarity" in www.grammaticalframework.org/lib/doc/synopsis.html.

Define a corresponding concrete grammar 'FoodsGer' for German.
