Not all restrictive ones will cause it to be definite

00Please check if my assumptions are correct.02br
02br
00I have an apple that has been sprayed with insecticide. -- Here, it is saying that he has one such apple that has been sprayed with insecticide.02br
02br
00I have the apple that I bought two days that has been sprayed with insecticide. -- Here, the assumption is that he bought only one apple tw days ago and that apple has been sprayed with insecticide.02br
02br
00The decline in the quality of apples grown here is due to its farmers' reluctance to be flexible with available technological farming advances -- Here, the word decline is definite because it is followed with a phrase that makes it definite. 02br
02br
00I have an apple of the finest quality. -- Here, the assumption is that he has one apple that is the finest in quality and don't know how many there are of the finest quality. There might be tons of apples that are of the finest quality out there.02br
02br
00So, my contention is that not all nouns that are followed by restrictive words, phrases or clauses are definite and have to look at the context to figure that out for each situation. 0-
