This removal is really strange.  I see you used `EvaluationLink` with only a `PredicateNode` inside also on a few other places...  What exactly does that mean?

Notice in my previous comment I proposed
```
(AtTimeLink
    (VariableNode "$qVar")
    (PredicateNode verb_instance)
)
```
but maybe that looks just as strange to other people...
