Given the task definition and input, reply with output. In this task, you're given passages that contain mentions of names of people, places, or things. Some of these mentions refer to the same person, place, or thing. Your job is to write questions that evaluate one's understanding of such references. Good questions are expected to link pronouns (she, her, him, his, their, etc.) or other mentions to people, places, or things to which they may refer. Do not ask questions that can be answered correctly without understanding the paragraph or having multiple answers. Avoid questions that do not link phrases referring to the same entity. For each of your questions, the answer should be one or more phrases in the paragraph, and it should be unambiguous.

Passage: In medieval Nubia, pottery and its decoration were appreciated as an art form. Until the 7th century, the most common pottery type found at Soba was the so-called "Red Ware". These wheel-made hemispherical bowls were made of red or orange slip and painted with separated motifs such as boxes with inner cross-hatchings, stylized floral motifs or crosses. The outlines of the motifs were drawn in black while the interiors were white. In their design, they are a direct continuation of Kushite styles, with possible influences from Aksumite Ethiopia. Due to their relative rarity, it has been suggested that they were imported, although they bear similarities to the pottery type, known as "Soba Ware", that succeeded them."Soba Ware" was a type of wheel-made pottery with a distinctive decoration very different from that found in the rest of Nubia. The shape of the pottery was diverse, as was the repertoire of painted decoration. One of the most distinctive features was the use of faces as painted decoration. They were simplified, if not geometric, in form and with big round eyes. This style is foreign to Makuria and Egypt, but bears a resemblance to paintings and manuscripts from Ethiopia. It is possible the potters copied these motifs from local church murals. Also unique was the application of animal-shaped bosses (protomes). Glazed vessels were also produced, copying Persian aquamaniles without reaching their quality. Beginning in the 9th century, "Soba Ware" was increasingly replaced by fine ware imported from Makuria.
What is the name of the pottery type that succeeded the most popular pottery until the 7th century?
