Answer:

There are a group of students in the class.

Answer 2

There are a group of students in the class.

• In the above sentence, "a group" is countable because they are in a countable form. Even though the material (students) is uncountable the form is 'countable.
• Countable nouns are for elements we can count by simply using numbers. They possess a singular and a plural form. The singular form can use a determiner such as "a" or "an". If you need to ask about the quantity of a countable noun, you ask "How many?" integrated with the plural countable noun.
• When a countable noun exists singular, we must use a word such as a/the/my/this with it
• Uncountable nouns are entities, theories etc that we cannot divide into distinct elements.

Hence, There are a group of students in the class.
