I recommend you eat ___ apple pie at this restaurant.
The correct answer is
I deem that it is because they are considering the set of different meals, and in this set in that particular restaurant there is only one
apple pie. In other words, in the menu of the restaurant you can find only one
But on the other hand, I could consider a lot of "instances" of the same pie ever made in this restaurant, in which case, I suppose, I should have used the indefinite article.
My questions are
- am I right about the reasons of using
the apple pie?
- how can I choose the set correctly? For example "Taking into account the plan of your apartment, you will definitely get a fast and strong WiFi connection provided that you buy ___ Google WiFi router". Is the set of companies producing wifi routers (google, mikrotik and so on...) considered here, in which case google wifi router is a single item on the list, or the set consisting of all instances / devices produced by all companies considered here, in which case I recommend buying one of these devices?
