What is the main idea of the following passage: 'The internet has revolutionized communication, allowing people to connect instantly from anywhere in the world. Social media platforms, like Facebook and Twitter, have further amplified this connectivity, enabling individuals to share information and ideas on a global scale.'

Correct Answer: C

Rationale: The correct answer is C because the passage highlights how the internet and social media have revolutionized communication globally, enabling instant connections and sharing of information on a global scale. It emphasizes the transformative impact of these technologies on communication, not just entertainment or the complexity of technology. Choice A is incorrect as the passage focuses on communication, not entertainment. Choice B is incorrect as it oversimplifies the role of social media in communication. Choice D is incorrect as the passage does not specifically address the increasing complexity of technology.

Correct Answer: C

Rationale: The primary purpose of using strong vocabulary in writing is to communicate your ideas clearly and precisely to the reader. While using complex words may impress the reader, the ultimate goal is effective communication. Clear communication ensures that the message is easily understood, removing any potential confusion or ambiguity. Choices A, B, and D are incorrect because the main focus should be on clarity and precision in conveying thoughts, rather than solely aiming to impress, confuse, or save space.

Correct Answer: B

Rationale: "Ironic" and "serious" are antonyms as they have opposite meanings. 'Ironic' refers to something that is contrary to what is expected or intended, while 'serious' indicates something grave or without humor. Therefore, the correct answer is B. Choice A is incorrect because synonyms are words with similar meanings. Choice C is incorrect as homonyms are words that sound the same but have different meanings, which is not the case for 'ironic' and 'serious'. Choice D is also incorrect as there is a relationship between the two words, making B the correct answer.

Correct Answer: C

Rationale: In this sentence, the word 'utter' best fits as it emphasizes the absolute and complete accuracy of the experiment. 'Utter' means total or complete, and in this context, it conveys a sense of total precision. Choices A, B, and D do not carry the same connotation of absolute precision. 'Extreme' and 'remarkable' may imply a high level of precision but not necessarily absolute or complete precision. 'Great' is a more general term that does not specifically emphasize the completeness of the precision required in conducting the experiment.

Correct Answer: B

Rationale: The correct answer is option B, 'I will have finished'. This choice correctly expresses a future event (finishing the project) that will be completed before another future point in time (next week). The future perfect tense 'will have finished' is used to show an action that will be completed before a specified future time. Choice A, 'I will be finishing', is incorrect as it indicates an ongoing action that will still be in progress by next week, which is not the intended meaning. Choice C, 'I am finishing', is incorrect as it indicates a present action that is ongoing, not a future event. Choice D, 'I would finish', is incorrect as 'would' is used for hypothetical situations or polite requests, which is not suitable in this context of a future project completion.
