Question 16

The pictorial quilts created by a former slave named Harriet Powers were remarkable for their bold storytelling techniques and their unique subject matter.

The use of "moreover" effectively indicates that Harriet Powers's quilts not only stand out but also add an additional layer of significance to the discussion about quilt making in the southern United States.

A) by contrast,

This option suggests a comparison that highlights differences between two subjects. However, the context does not focus on contrasting Powers's work with another type of quilt; instead, it emphasizes the remarkable qualities of her quilts as an addition to the existing narrative of quilt making.

B) for example,

This phrase typically introduces a specific instance that illustrates a broader point. In this case, it does not fit well because the sentence already presents Powers's quilts as notable without needing to reference them as mere examples among others.

C) it so happens,

This phrase implies a casual or coincidental relationship, which does not appropriately convey the significance of Harriet Powers's contributions to quilt making. The sentence aims to assert the impressive qualities of her work, rather than suggesting a happenstance occurrence.

D) moreover,

This option successfully enhances the sentence by indicating that Powers's quilts add further value and depth to the discussion about quilt making. It indicates that her work is not just another example but is significant in its own right, aligning perfectly with the sentence's intent.

Conclusion

The choice of "moreover" effectively links Harriet Powers's unique contributions to the broader context of quilt making in the southern United States, emphasizing the importance of her storytelling techniques and subject matter. The other options fail to convey the significance needed in this context, either by suggesting contrast, casualness, or simply providing examples. Thus, "moreover" is the most appropriate choice.
