Questions: Quantum computing is a type of computing that uses quantum-mechanical phenomena, such as superposition and entanglement, to perform operations on data. Though it sounds more science fiction than fact, experimental quantum computers have already demonstrated capabilities surpassing those of traditional computers in specific tasks. experts generally agree that fully operational quantum computers, capable of handling a broad range of real-world applications, remain years away. Which choice completes the text with the most logical transition? Choose 1 answer: (A) Moreover, (B) However, (C) Consequently, (D) In other words

The answer is B: However,

Explanation for each option:

(A) Moreover: This word is used to add information that supports or continues the previous statement. In this context, it would suggest that the following sentence is an additional point supporting the idea that quantum computers have surpassed traditional computers, which is not the case here.

(B) However: This word is used to introduce a contrast or exception to the previous statement. It is the most logical choice because the text first mentions the capabilities of experimental quantum computers and then contrasts this with the fact that fully operational quantum computers are still years away.

(C) Consequently: This word indicates a result or effect of the previous statement. It would not fit here because the second sentence does not describe a consequence of the first.

(D) In other words: This phrase is used to rephrase or clarify the previous statement. It would not be appropriate here because the second sentence is not a rephrasing of the first; instead, it presents a contrasting idea.
