Team is a collective noun and takes singular verb 'has' not 'have' in British English, though American English allows both. The sentence should read 'The team has completed.'

Structure is the correct spelling. It refers to the framework or design of a building.

Correct contraction is 'doesn't' (does not) for third person singular. 'Supplies' is plural, so verb should be 'are' not 'is'.

Ephemeral means lasting for a very short time. Transient has the same meaning. Permanent and eternal are antonyms.

The logical sequence is: 'The festival celebrates the victory of good over evil and attracts millions of devotees every year.' This follows Subject-Verb-Object structure.

'Team' is a collective noun treated as singular, so 'is' is correct, not 'are'.

Option D has correct subject-verb agreement and proper verb form. All other options have grammatical errors.

'Not only...but also' is the correct parallel structure for presenting two equal ideas.

'Ameliorate' means to make something better or improve, similar to 'improve'.

The passage explicitly states that 'digital literacy remains unevenly distributed across urban and rural areas,' which is presented as a limitation.
