Q1  15
Q1 15

Question 1: Which of the following is a complete sentence, not a sentence fragment?

Question 1 options
'The children played in the park' is correct because it contains a subject ('The children'), a verb ('played'), and expresses a complete thought. The other options are fragments because they each lack either a subject, a verb, or a complete thought.
Q2 15

Question 2: A sentence fragment is incomplete because it ___.

Question 2 options
'lacks a subject, a verb, or a complete thought' is correct because a fragment is missing at least one of these essential elements. Fragments may begin with capital letters and end with punctuation, so those are not the defining problems.
Q3 15

Question 3: A sentence fragment always looks different from a complete sentence because it never starts with a capital letter.

Question 3 options
False because sentence fragments do begin with a capital letter and end with punctuation, which is exactly why they can be mistaken for complete sentences. The problem is that they lack a subject, a verb, or a complete thought.
Q4 15

Question 4: Why is 'During the school holidays.' considered a sentence fragment?

Question 4 options
'It places the reader in time but has no subject or verb' is correct because this phrase is a prepositional phrase that provides time information but lacks the subject-verb relationship needed for a complete thought. It cannot stand alone as a sentence.
Q5 15

Question 5: Arrange the words to make a correct sentence:

Question 5 options
  • every evening.
  • study together
  • Some students in the library

Drag items or use arrows to arrange them in the correct order.

The correct order is 'Some students in the library study together every evening.' because 'Some students in the library' is the subject phrase, 'study together' is the verb phrase, and 'every evening' is the time expression. This structure avoids a fragment by including both a subject and a verb.
Q6 15

Question 6: Which sentence is grammatically correct and NOT a sentence fragment?

Question 6 options
'My brother works at the local hospital' is correct because it has a clear subject ('My brother') and a verb ('works'), forming a complete thought. The other options are fragments: they are missing a main verb or express an incomplete idea.
Q7 15

Question 7: A student writes: 'Because the exam was very difficult. Many students failed.' Which revision correctly fixes the fragment?

Question 7 options
'Because the exam was very difficult, many students failed.' is correct because the dependent clause ('Because the exam was very difficult') must be joined to the independent clause ('many students failed') with a comma, forming one complete sentence.
Q8 15

Question 8: Which sentence correctly uses a dependent clause as part of a complete sentence, rather than as a fragment?

Question 8 options
'When the rain stopped, we went for a walk' is correct because the dependent clause 'When the rain stopped' is attached to the independent clause 'we went for a walk,' forming a complete sentence. The other options leave the dependent clause standing alone.
Q9 15

Question 9: Put the words/clauses in the correct order to form a complete sentence:

Question 9 options
  • After the concert finished,
  • slowly left
  • the audience
  • the hall.

Drag items or use arrows to arrange them in the correct order.

The correct order is 'After the concert finished, the audience slowly left the hall.' because a subordinate clause beginning with 'After' must be followed by a comma and then the main independent clause. This avoids the fragment error of leaving the subordinate clause alone.
Q10 15

Question 10: The group of words 'Waiting outside the office for more than an hour' is a fragment. What is the best way to complete it into a full sentence?

Question 10 options
'She was waiting outside the office for more than an hour.' is correct because adding the subject 'She' and the auxiliary verb 'was' gives the -ing verb ('waiting') the support it needs to function as the main verb, creating a complete sentence.
Q11 15

Question 11: Which statement about sentence fragments is TRUE according to standard English grammar rules?

Question 11 options
'A fragment can be corrected by adding a missing subject, verb, or by attaching it to an independent clause' is correct. Fragments must have all three: a subject, a verb, and a complete thought. Simply being short or using a conjunction does not make a group of words a fragment.
Q12 15

Question 12: Fragment: 'The new teacher from Brazil.' → Rewrite as a complete sentence: 'The new teacher from Brazil ___.'

Question 12 options
'speaks three languages fluently' is correct because it adds a main verb ('speaks') and a complete predicate, turning the noun phrase fragment into a full sentence with a subject and verb. The other options either remain incomplete or add only a description without a true predicate.
Q13 15

Question 13: Match each sentence or group of words to the correct grammar label.

Question 13 options
The students finished their homework before dinner.
Early in the morning before sunrise.
Although she studied hard for the test.
Several boxes of old books and magazines.
Fragment missing a subject and verb
Complete sentence (subject + verb + complete thought)
Fragment – noun phrase with no verb
Fragment – standalone subordinate clause

Select an item on the left, then tap its match on the right.

A complete sentence needs a subject, a verb, and a complete thought. Fragments are missing one or more of these: they may be missing a subject, a verb, a main clause, or may be a standalone subordinate clause.
Q14 15

Question 14: Sentence fragments should always be avoided in all types of writing, including novels and informal texts.

Question 14 options
False because while fragments must be avoided in formal and academic writing, they can appear in creative writing such as novels and in informal contexts for stylistic effect. The key rule is that they must be avoided in formal written work.
Q15 15

Question 15: Which of the following best describes the difference between these two groups of words? A: 'She left the office early.' B: 'Leaving the office early.'

Question 15 options
'A is a complete sentence; B is a fragment because it has no subject and uses an -ing verb without an auxiliary' is correct. An -ing verb form like 'leaving' cannot act as the main verb of a sentence without an auxiliary verb (e.g., 'was leaving'), and the phrase has no subject.
