This question was previously asked in
CDS I 2020 Elementary Mathematics Previous Year Paper (02-Feb-2020)
The correct answer is

No sooner did the teacher enter the classroom than all the students stopped talking.

Combining Sentences with 'No Sooner... Than'

The question asks us to combine two separate sentences into one grammatically correct and meaningful sentence. The two sentences describe a sequence of events:

  1. The teacher entered the classroom.
  2. All the students stopped talking.

We need to find the option that best shows that the second event happened immediately after the first event.

Analyzing the Options for Correct Sentence Combination

Let's look at each option and see how it combines the two sentences and if it accurately reflects the relationship between the events.

  • Option 1: No sooner did the teacher enter the classroom than all the students stopped talking.

    This sentence uses the structure 'No sooner... than'. This structure is used to indicate that one event happened immediately after another. When 'No sooner' starts a sentence, we use inversion (auxiliary verb + subject + main verb). 'did the teacher enter' follows this rule (did + subject 'teacher' + base verb 'enter'). The second part of the structure uses 'than' followed by the consequence ('all the students stopped talking'). This option correctly shows that the students stopped talking immediately after the teacher entered.

  • Option 2: As soon as the teacher entered the classroom all students were asked to stop talking.

    This option uses 'As soon as', which also indicates immediate sequence. However, the second part says 'all students were asked to stop talking'. This changes the meaning of the original sentences. The original sentences state that the students *stopped* talking, not that they *were asked* to stop talking. This option introduces an action by the teacher (asking) that wasn't in the original sentences.

  • Option 3: All students stopped talking as the teacher enters the classroom.

    This option uses 'as' to show simultaneous actions or actions happening around the same time. However, the main problem here is the tense. The first part 'All students stopped talking' is in the simple past tense. The second part 'as the teacher enters the classroom' is in the simple present tense ('enters'). To combine two past events, both clauses should generally be in a past tense. Using 'enters' makes this sentence grammatically incorrect in this context.

  • Option 4: No sooner did the students stop talking than the teacher entered the classroom.

    This option uses the 'No sooner... than' structure correctly in terms of grammar and inversion ('did the students stop'). However, it completely reverses the order of the events described in the original sentences. It says that the students stopped talking *before* the teacher entered, which is not what the original sentences imply happened. The teacher entered first, and *then* the students stopped talking.

Evaluating the Best Combination

Comparing the options, Option 1 is the only one that correctly combines the two sentences while maintaining the original meaning and sequence of events, using the appropriate grammatical structure ('No sooner... than' with inversion) for expressing immediate succession in the past.

Option Combination Structure Meaning/Sequence Grammar Correctness
1 No sooner... than (with inversion) Teacher entered first, then students stopped immediately. Correct sequence. Correct (Past Tense, Inversion) Correct
2 As soon as Teacher entered first, then students *were asked* to stop. Changes meaning. Grammatically correct structure but changes original meaning. Incorrect (Meaning change)
3 ...as... Students stopped, then teacher enters. Incorrect tense and sequence implication. Incorrect (Tense mismatch) Incorrect (Grammar & Meaning)
4 No sooner... than (with inversion) Students stopped first, then teacher entered. Incorrect sequence. Grammatically correct structure but reverses sequence. Incorrect (Sequence)

Based on this analysis, Option 1 is the most accurate and grammatically correct combination of the two given sentences, correctly showing the immediate sequence of the teacher entering the classroom followed by the students stopping talking.

Revision Table: Key Combination Structures

Structure Usage Example (Past Events) Note
No sooner... than Indicates one action happens immediately after another. Often uses inversion when starting a sentence.

No sooner had I arrived than it started raining.

No sooner did he see me than he ran away.

Inversion: Aux verb + Subject + Main verb
Hardly/Scarcely/Barely... when/before Similar to 'No sooner... than', indicates immediate succession. Also uses inversion.

Hardly had I left the house when I remembered the keys.

Scarcely had she finished speaking before the lights went out.

Inversion: Aux verb + Subject + Main verb
As soon as Indicates immediate succession. More common in everyday language than 'No sooner', 'Hardly', etc. No inversion required.

As soon as I arrived, it started raining.

As soon as he saw me, he ran away.

Simple sentence structure.

Additional Information: Sentence Combining Techniques

Combining sentences helps make writing more fluent and shows the relationship between ideas. Different conjunctions and structures can be used depending on the relationship you want to show:

  • Showing sequence: 'and then', 'after', 'before', 'as soon as', 'No sooner... than', 'Hardly... when'.
  • Showing cause and effect: 'because', 'since', 'as', 'so', 'therefore', 'consequently'.
  • Showing contrast: 'but', 'however', 'although', 'even though', 'whereas', 'while'.
  • Showing purpose: 'to', 'in order to', 'so that'.
  • Showing condition: 'if', 'unless', 'provided that'.

Choosing the right structure depends on the specific meaning and emphasis you want to convey when combining sentences.
