Part-I: English — Grammar Usage & Sentence Structuring (Q1–Q10)
Q1. Choose the correct form of the verb: ‘Neither the students nor the teacher ___ arrived yet.’
A. have
B. has ✓
C. are
D. were📖 Explanation: When ‘neither…nor’ connects subjects, the verb agrees with the closer subject (‘the teacher’ = singular), so ‘has’ is correct.
Q2. Select the sentence with correct use of the subjunctive mood:
A. I wish I was taller.
B. If I were you, I would study harder. ✓
C. She acts as if she was the principal.
D. It is essential that he attends the meeting.📖 Explanation: The subjunctive ‘were’ (not ‘was’) is used in hypothetical conditions. ‘If I were you’ is standard formal English subjunctive.
Q3. Which sentence uses a dangling modifier?
A. Running fast, she won the race.
B. Walking along the road, the trees looked beautiful. ✓
C. Exhausted by the exam, the student slept immediately.
D. Having studied all night, he passed with distinction.📖 Explanation: ‘Walking along the road’ dangles because trees cannot walk. The participial phrase has no logical subject to modify.
Q4. Choose the correct punctuation: ‘The results were as follows___ pass, fail, and incomplete.’
A. Comma
B. Semicolon
C. Colon ✓
D. Dash📖 Explanation: A colon is used to introduce a list or explanation that follows a complete independent clause.
Q5. The passive voice of ‘They are building a new school’ is:
A. A new school was being built.
B. A new school is being built. ✓
C. A new school has been built.
D. A new school will be built.📖 Explanation: Present continuous active (‘are building’) converts to present continuous passive (‘is being built’). The tense must remain consistent.
Q6. The word ‘loquacious’ most nearly means:
A. Silent
B. Talkative ✓
C. Logical
D. Lazy📖 Explanation: Loquacious means tending to talk a great deal — talkative or garrulous. It comes from the Latin ‘loqui’ meaning to speak.
Q7. Which of the following is a complex sentence?
A. She studied and passed.
B. She studied hard, but she failed.
C. Although she studied hard, she failed. ✓
D. She studied; she passed.📖 Explanation: A complex sentence has one independent clause and at least one dependent clause. ‘Although she studied hard’ is the subordinate clause here.

C. Synthesis/Create
D. Evaluation ✓📖 Explanation: In Bloom’s original (1956) taxonomy, Evaluation is the highest level. In the revised version (Anderson & Krathwohl, 2001), ‘Create’ is at the top, but Evaluation remains the second highest.
Q36. The learning theory that emphasizes conditioning through stimulus-response is:
A. Constructivism
B. Cognitivism
C. Behaviourism ✓
D. Humanism📖 Explanation: Behaviourism (Pavlov, Skinner, Watson) focuses on observable behaviour shaped through stimulus-response conditioning, reinforcement, and punishment — ignoring internal mental states.
Q37. The most effective approach to classroom management is:
A. Reactive — punishing misbehaviour after it occurs
B. Preventive — establishing clear rules and routines proactively ✓
C. Ignoring all misbehaviour
D. Strict authoritarian control only📖 Explanation: Research consistently shows that preventive classroom management — setting clear expectations, routines, and a positive climate before problems arise — is far more effective than reactive punishment.
Q38. Positive reinforcement in the classroom means:
A. Removing something unpleasant to increase behaviour
B. Adding something pleasant to increase desired behaviour ✓
C. Punishing unwanted behaviour
D. Ignoring all student behaviour📖 Explanation: Positive reinforcement adds a pleasant stimulus (praise, reward, recognition) after a desired behaviour, increasing the likelihood of that behaviour recurring (Skinner’s operant conditioning).
Q39. A lesson plan should primarily be aligned with:

C. School administration preferences
D. Teacher’s personal teaching style📖 Explanation: Effective lesson planning uses backward design — every activity, resource, and assessment must align with clearly stated learning objectives and the learners’ needs and prior knowledge.
Q40. Which teaching method is most appropriate for developing higher-order thinking skills?
A. Rote memorisation
B. Lecture method
C. Problem-based learning (PBL) ✓
D. Copying notes📖 Explanation: PBL requires students to analyze, evaluate, and synthesize information to solve real-world problems, directly engaging Bloom’s higher-order levels (Analysis, Evaluation, Creation).
Q41. Scaffolding in teaching refers to:
A. Building physical structures in class
B. Providing temporary support to students that is gradually removed as competence grows ✓
C. Strict grading
D. Group seating arrangements📖 Explanation: Scaffolding (linked to Vygotsky’s ZPD) involves targeted temporary support — hints, models, worked examples — that is progressively withdrawn as the learner becomes more independent and competent.
Q42. Formative assessment is conducted:
A. Only at the end of the year
B. During the learning process to monitor progress ✓
C. Only for grading purposes
D. Before instruction begins📖 Explanation: Formative assessment is ongoing and conducted during the instructional process. It provides feedback to both teacher and student to guide and improve learning — it is ‘assessment for learning’.
Q43. Validity in assessment means:
A. The test gives consistent results
B. The test measures what it is intended to measure ✓
C. The test is easy to administer
D. The test is long enough📖 Explanation: Validity is the degree to which an assessment tool accurately measures the specific construct or learning outcome it is designed to measure. It is the most fundamental quality of a good test.
