The error lies in part (c).

In the given section, ‘grown’ must be changed to ‘growing’ as the sentence refers present perfect continuous tense. The present perfect continuous is formed with have/has been and the -ing form of the verb. We normally use the present perfect continuous to emphasise that something is still continuing in the present.

The given sentence is saying that ‘Christianity’ is growing in China even with the restrictive religious policy of the Chinese Communist Party.

Therefore, the correct sentence will be: “The surge of Christianity in China has baffled the scholarly community for several decades as Christianity has been growing by leaps and bounds despite the restrictive religious policy of the Chinese Communist Party.”

The error lies in part (a). "emphasized on" should be changed to "emphasized" as "on" is unnecessary. The verb emphasize is not used with the preposition on.

It is a transitive verb, meaning that it takes a direct object.

Ex- The report emphasizes the need for political stability.

Therefore, the correct sentence will be: “The teacher emphasized the importance of regular attendance to the students.”

The sentence has no errors.

The error lies in part (c). The word "confidence" is a noun, but in this context, the sentence requires an adjective to describe the state of the team. The adjective form of "confidence" is "confident." Therefore, the correct construction is: "and they're confident of their victory."

Therefore, the correct sentence will be: “The team has been practicing hard for the upcoming match, and they're confident of their victory.”

The error lies in part (a). The error in the sentence is a mismatch between the adjective "diligent" and the verb "conducted." "Diligent" is an adjective, but in this context, the adverb form "diligently" is required to describe how the scientists conducted the experiments. Adverbs typically modify verbs, adjectives, or other adverbs, providing more information about the manner in which an action is performed.

Therefore, the correct sentence will be: “Scientists diligently conducted experiments, analyzed data, and collaborated to unravel the mysteries of the universe.”

The correct answer is: “joined in solidarity to protest their”.

The correct usage of preposition after ‘join’ is ‘in’. ‘Join in’ is a phrasal verb, which means ​to take part in an activity with other people. Also, ‘joined’ is the correct grammar form here as the sentence is in past tense. ‘to’ preposition is used to refer the purpose, aim of something, thus, ‘to protest’ is the correct form.

‘Their’ means belonging, ‘there’ means in or at that place. Hence, ‘their’ is the correct form.

The correct answer is: “gracefully danced across the stage”.

The given sentence is in past tense, hence needed a past tense verb(danced). ‘gracefully’ must be in adverb form because it is modifying the verb dance. ‘across’ is the correct preposition here, as it refers from one side to the other of. Through means moving in one side and out of the other side of (an opening, channel, or location). Above means in extended space over and not touching.
