Choose the correct sentence from the options below:

An uncountable (mass) noun names a substance, an abstract idea, or a whole category that cannot be individually counted. Such nouns have no plural form, are not preceded by the indefinite article "a/an", and always take a singular verb — even when they end in "-s" (like news) or refer to many items collectively (like furniture). A single instance is instead expressed with a separate countable noun or a "piece/item of ___" phrase.

1. "I am learning a new poetry." — poetry is uncountable, so it cannot take the article "a"; a single composition is a "poem", not "a poetry".

2. "These news are good." — news is uncountable despite its "-s" ending, so it needs the singular demonstrative "this" and the singular verb "is", not "these ... are".

3. "All the furniture was destroyed." — furniture is uncountable, so it combines with the non-count quantifier "all the" and the singular verb "was", which is exactly how this sentence is built.

4. "The sceneries of Kashmir are very charming." — scenery is uncountable and has no plural form, so "sceneries ... are" is non-standard; the correct form is "the scenery ... is".

Cross-check with the standard non-count test: one can say "much poetry", "much news", "much furniture", and "much scenery", but not "many poetry/news/furniture/scenery" — confirming all four nouns are non-count. Checking each option's article and verb against this non-count behaviour shows that only one sentence keeps both the article usage and the subject-verb agreement correct throughout.

"All the furniture was destroyed." is therefore the grammatically correct sentence.
