The error is in part (a). 'Travel' is generally an uncountable noun or a verb; when referring to a specific trip, 'The journey' or 'The trek' is more appropriate. Alternatively, 'Travel' without the article 'The' might be used, but 'The travel' is unidiomatic here.

To identify the part that contains an error, we need to carefully analyze each option and determine if there is any grammatical mistake or inconsistency in the sentence.

Option A) (a) disappeared - This option does not contain any obvious grammatical error.

Option B) (b) and the sun started - This option does not contain any obvious grammatical error.

Option C) (c) to shine - This option does not contain any obvious grammatical error.

Option D) (d) - This option does not contain any obvious grammatical error.

Option E) All correct - This option suggests that there is no error in the given sentence.

Analyzing the options, we can see that Option E states that all parts are correct. Therefore, the correct answer is:

E. e

According to Option E, all parts of the sentence are correct, indicating that there is no error in the given sentence.

The construction 'No sooner' requires the inverted word order 'No sooner did we enter' not 'No sooner we entered'. The correct structure is: 'No sooner did we enter than he got up and left the room.' The auxiliary verb 'did' is mandatory after 'No sooner' at the beginning of a sentence.

The sentence is grammatically correct. 'The advent of electricity' is a standard phrase, and the present perfect 'has definitely improved' correctly describes a continuing state or recent change. No error is present in parts a, b, c, or d.

'Advanced by' is the correct preposition when something is moved to an earlier time by a specific duration. The structure 'advanced + time period' requires 'by' to show the extent of the change. 'On' and 'of' are not used with 'advanced' in this context.

'Beside' means 'next to' or 'at the side of,' which is the only logical position in this context. The sentence describes someone sitting next to a dead body. 'Front' and 'behind' don't convey the necessary spatial relationship.

The present perfect tense 'has' requires the past participle form of the verb. 'Given' is the past participle of 'give'. 'Give' (base), 'gave' (past), and 'giving' (present participle) are grammatically incorrect here.

'Since' functions as a conjunction meaning 'because' or 'given that,' which fits the context perfectly. It introduces a reason that compels belief. 'For' can also mean 'because' but is more formal and less natural here. 'From' doesn't make sense.

The conjunction 'that' is used to introduce a noun clause acting as the object of the verb 'hear'. It reports the information received. 'Whether' would imply doubt, which doesn't fit the declarative nature of the statement.

To solve this question, the user needs to identify the appropriate conjunction to connect the two parts of the sentence and make it grammatically correct.

In this sentence, the best conjunction to use is "that", which is option B. Therefore, the answer is:

The Answer is: B. that

Explanation:

Option A "if" is a conditional conjunction that is used to introduce a condition that must be met before something else happens. It is not the right conjunction to use in this sentence.

Option B "that" is a conjunction that is used to introduce a subordinate clause that provides additional information about the main clause. In this case, "that" introduces the clause "the earth is round" which is the fact being stated in the sentence.

Option C "because" is a conjunction that is used to introduce a subordinate clause that explains the reason for the main clause. It does not fit the sentence structure because there is no reason being given in the sentence.

Option D "those" is a pronoun that is used to refer to more than one thing that has already been mentioned. It does not fit the sentence structure because there is nothing to refer to in the sentence.

The sentence shows a contrast between effort and result. 'But' is the coordinating conjunction used to introduce a phrase that contrasts with what has already been mentioned. 'Because' and 'and' do not convey this opposition.

This is a first conditional sentence (If + present simple, will + verb). 'If you go' sets the condition, and 'you will see' describes the certain result in the future.

'Lest' requires the subjunctive mood, which uses the base form of the verb. The phrase 'lest you fall' means 'so that you don't fall' or 'for fear that you might fall.' The base form 'fall' is grammatically required after 'lest.'

When a proper noun is used as a common noun to denote a person with similar qualities (a metaphor), the definite article 'the' is used. Here, she is being compared to the specific famous person 'Shri Devi'.

The word 'expensive' begins with a vowel sound /e/, so the indefinite article 'an' is required. 'A' is used before consonant sounds, and 'the' would only be used if a specific sari was previously mentioned.

'Otherwise' correctly connects two contrasting ideas - the action taken and the consequence that would have occurred without it. The sentence means 'Mohit saved her; if not for that, he would have drowned.' The other options don't establish this logical relationship.

The past participle of 'overflow' is 'overflowed'. 'Overflown' is the past participle of 'overfly' (to fly over). The stored answer 'Over flown' is technically a common error; the correct word should be 'overflowed', but among the choices, it is the intended distractor/answer.

In this context, 'would' expresses a future possibility or a conditional result of human progress. While 'will' or 'can' could work in different contexts, 'would' is often used in formal writing to discuss potential future achievements.

The sentence refers to a completed historical event (the moon missions). The simple past 'spent' is the appropriate tense. 'Spend' and 'are spending' imply habitual or current action, which does not fit the context of lunar exploration.
