Grammatically, I think "that" has to be modifying "elementary particles," because you generally can't jump over a verb to make "that" modify "neutrinos." In fact, this example is the only thing preventing me from saying that you definitely can't jump over a verb like this.JbhB682 Wrote:Hi Experts - with option A , what is "THAT" referring to - neutrino's or elementary particles ?
I thought "THAT" referred to elementary particles and subsequently eliminated option A
My Reasoning : it cannot be elementary particles that are produced in nuclear reactions. It cannot be elementary particles that interact weakly with matter
It is the neutrino's specifically that are produced in nuclear reactions. It is the neutrino's that interact weakly with matter.
Hence i eliminated A
Where is the gap in my logic ?
Logically, however, I'd say there's not much difference between those two nouns: the verb "are" basically equates them. And since they are equivalent nouns, your reasoning above is overkill. Yeah, it's particles that are produced in nuclear reactions, but we were told that the particles produced are neutrinos.
Here's another example:
Celosia are edible and ornamental plants that are part of the amaranth family and that are named for their flame-like flower heads.
Both of the "that" modifiers specifically pertain to celosia, not to "edible and ornamental plants" in general.
