I dont get why they refer to people as "it". It is putting the jam..... He is putting the jam....
Could not agree more, looks like a mistake in the answer For "He puts" to be counted as a mistake, there should be more context about what happens in the text
Why is it "the bag"? Cannot "a bag" also be a correct solution? As "In" always takes the indefinite form, how can you tell?
You can tell:
El pune borcanele într-o pungă = He puts the jars in a bag.
Why „într-o” instead of „în o”, you ask? Well, because it is officially a contraction of „în o”. I guess this is one of the idiosyncrasies of the Romanian language that you will just have to learn.
If you use only „în pungă”, „din pungă”, „pe pungă” .... (you get the idea), the noun is in fact always definite, even if there is no article in this case. You do have to use the article if there is also an adjective describing the noun: „în punga mea” = „in my bag”.
Hope this explanation helps.
