To determine whether a sentence has a transitive or intransitive verb, we need to determine if the verb is taking an object or not.
1) "Drawing is a very interesting subject." - This sentence is intransitive because the verb "is" does not have a direct object.
2) "Amal is adorable to his father." - This sentence is also intransitive because the verb "is" does not have a direct object.
3) "A fisherman is a hardworking man." - This sentence is intransitive because the verb "is" does not have a direct object.
4) "Muhammad is not as strong as his brother." - This sentence is intransitive because the verb "is" does not have a direct object.
5) "There are many roses in my aunt's garden." - This sentence is transitive because the verb "are" has a direct object, "roses."
6) "This apple is very sweet." - This sentence is intransitive because the verb "is" does not have a direct object.
In regards to the nouns:
- "Air" is an abstract noun. Abstract nouns refer to things that are not tangible or physical, such as ideas, emotions, or concepts.
- "Ocean" is a concrete noun. Concrete nouns refer to things that can be perceived through the senses, such as objects, animals, or substances.
