Question 20

Moreover

The word "moreover" effectively indicates that the information about Jimmy Page playing the theremin adds to the previously mentioned uniqueness of the instrument, emphasizing its significance in the context of music history.

A) by contrast,

This option implies a comparison or opposition between two different ideas, which does not fit with the context. The statement about Jimmy Page does not contrast with the previous information about the theremin's unique qualities.

B) for example,

While "for example" could suggest that Jimmy Page's use of the theremin is one instance of its uniqueness, it does not convey the additive nature of the statement. The context requires a transition that reinforces the connection rather than merely providing an example.

C) it so happens,

This phrase introduces an element of chance or coincidence, which is not appropriate here. The inclusion of Jimmy Page's use of the theremin is not a random occurrence but rather a relevant detail that enriches the discussion of the instrument.

D) moreover,

This option is suitable as it indicates that the following information about Jimmy Page enhances the understanding of the theremin's importance in music. It connects the two ideas seamlessly and emphasizes the relevance of the example given.

Conclusion

The choice "moreover" is the most effective transition in this context as it highlights the significance of Jimmy Page's use of the theremin in relation to its unique characteristics. The other options fail to convey this additive relationship and either suggest contrast, coincidence, or merely an example without reinforcing the connection. Thus, "moreover" is the most appropriate choice.
