The question presents two sensory perceptions and asks us to identify the corresponding taste/texture terms.
First part: which sensation is often described as tart or sour? Among common taste descriptors, sour is the one associated with tartness or tanginess, as opposed to salty (salinity), sweet (sugariness), bitter (sharpness), umami (savory), or astringency (dry mouth feel). Therefore, the term that fits tartness is sour, not the other options.
Second part: which sensation is described as a rough, dry, chalky mouthfeel? Astringency is the perceptual category that produces that drying, puckering, rough sensation in the mouth, commonly linked to high tannin content or certain polyphenols. Other descriptors like salty, umami, bitter, sweet, or sour do not capture the dry, puckering mouthfeel characteristic of astringency, so they do not fit this description.
In summary, for the first blank, sour is the appropriate choice, while for the second blank, astringency is the correct descriptor. This aligns with standard taste and oral sensation classifications, where sour corresponds to tart flavors and astringency to the dry mouthfeel.
