The theremin, an electronic musical instrument invented by Leon Theremin in 1928, is unique in that it is played without physical contact. The musician (occasionally referred to as a thereminist) stands in front of the instrument and moves his or her hands in the proximity of two metal antennas. The distance from one antenna determines frequency (pitch), and the distance from the other controls amplitude (volume). Led Zeppelin guitarist Jimmy Page played a theremin on the rock group"s 1970s hit song "Whole Lotta Love."

Rationale

Moreover

The word "moreover" effectively introduces additional information that builds on the idea that the airplane is inspired by the flight of birds, emphasizing the connection between nature and technological advancement.

A (by contrast,) YOUR ANSWER

"By contrast" suggests a comparison that highlights differences between two ideas or subjects, which is not appropriate in this context. The sentence discusses a relationship of inspiration rather than contrasting two opposing concepts.

B (for example,) YOUR ANSWER

The phrase "for example" introduces a specific instance that illustrates a broader point. However, the sentence already presents the airplane as an example of inspiration derived from birds; therefore, using "for example" would be redundant and less effective than "moreover."

C (it so happens,) YOUR ANSWER

"It so happens" conveys a sense of coincidence or chance, which does not accurately reflect the intended meaning of the sentence. The relationship between the flight of birds and the invention of airplanes is a result of deliberate inspiration rather than a mere happenstance.

D (moreover,) CORRECT

"Moreover" indicates that the airplane serves as an additional point that amplifies the initial statement about the inspiration drawn from birds. It seamlessly connects the two ideas, reinforcing the notion that observing birds led to significant technological advancements in aviation.

Conclusion

The transition word "moreover" aptly enhances the flow of the sentence by linking the inspiration from birds to the development of the airplane. Each of the incorrect choices fails to capture the intended meaning or context, making "moreover" the superior option for conveying the relationship between these ideas effectively.
