Hi, Blue_Delta_47, and welcome to G.E.
I'm not sure that I understand what you mean by:
a non-restrictive clause is used when referring to something that is expected to be found in an object
Non-restrictive or non-defining clauses are used to add extra information about the noun. I personally found David's comment and the ensuing solution perfect:
What I think would improve the sentence from a stylistic standpoint is making one idea the main idea and the other the background idea
The fact that some information appears between commas in a non-restrictive clause does not make it sound as information that belongs to the public domain, that is, as information that is known by everyone and has therefore secondary importance when making a scientific claim (if that is what you mean by "something that is expected to be found in an object"). (A) and (B) merely provide a more elegant version of the idea you want to convey: instead of using a compound predicate including the rather simple conjunction "and," why not use a more complex sentence with a relative clause? Please note that we are not speaking about grammatical correctness (your original sentences are grammatically correct), but about improving the style.
Thanks GUSTAVO, for your clarification. I was on my placement in an aged care facility, so I didn't have time to check the reply.
What I was trying to ask about was the distinct characteristics of non-relative clauses and relative clauses. Although I've learnt about both, I am still rather confused about their usage.
- A non-relative clause is characterised by pronouns when, which,... followed by a clause, and a comma before the pronoun and the other at the end of the clause itself. What I was wondering was whether 'non-relative clause' to add extra information about 'the obvious/predictable/unique/universal' features of an object.
- Example is 'lions can only eat meat'. In this case I can put the info only eat meat as part of the non-relative clause:
- Lions, which only eat meat, are fine predators
- However, another example is "lions that are genetically modified only eat plants". In this case I cannot use non-relative clauses because 'genetically modified only eat plant' is not 'universally/globally known or understanding or features of regular lions'. Thus:
- Lions, which are genetically modified, only eat plants.
- Lions, which only eat plants, are genetically modified.
- However, it is correct to say:
- Lions, which only eat meats, may eat plants if they are genetically modified.
Am I understanding the situation the correct way?
