Question: What type of category does Sequoia and Nandina have in common?

<P0-S0> Sequoia is a genus of redwood coniferous trees in the subfamily Sequoioideae of the family Cupressaceae. <P0-S1>  The only extant species of the genus is "Sequoia sempervirens" in the Northern California coastal forests ecoregion of Northern California and Southwestern Oregon in the United States. <P0-S2>  The two other genera, "Sequoiadendron" and "Metasequoia", in the subfamily Sequoioideae are closely related to "Sequoia". <P0-S3>  It includes the largest trees in the world. <SEP> <P1-S0> Nandina domestica ( ) commonly known as nandina, heavenly bamboo or sacred bamboo, is a species of flowering plant in the family Berberidaceae, native to eastern Asia from the Himalayas to Japan. <P1-S1>  It is the only member of the monotypic genus Nandina. <SEP> <P2-S0> Category utility is a measure of "category goodness" defined in and . <P2-S1>  It attempts to maximize both the probability that two objects in the same category have attribute values in common, and the probability that objects from different categories have different attribute values. <P2-S2>  It was intended to supersede more limited measures of category goodness such as "cue validity" (; ) and "collocation index" . <P2-S3>  It provides a normative information-theoretic measure of the "predictive advantage" gained by the observer who possesses knowledge of the given category structure (i.e., the class labels of instances) over the observer who does "not" possess knowledge of the category structure. <P2-S4>  In this sense the motivation for the "category utility" measure is similar to the information gain metric used in decision tree learning. <P2-S5>  In certain presentations, it is also formally equivalent to the mutual information, as discussed below. <P2-S6>  A review of "category utility" in its probabilistic incarnation, with applications to machine learning, is provided in . <SEP> <P3-S0>  In C category, individually 4 elements have to be performed ( one from each type), A or B difficulty, and in groups, two are optional. <P3-S1>  In each categories there are group and individual routines. <P3-S2>  (or Senior in A category)), and categories ( which are based on knowledge). <P3-S3>  In B category individually 8 elements need to be performed ( two from each type) A-D difficulty ( but max. <P3-S4>  Routines get evaluated in three categories: technique, artistry, and content (execution of elements). <P3-S5>  All elements are graded by difficulty from A to H. <P3-S6>  Competition is divided by age groups (I. to IX. <P3-S7>  In C Category (here group routines are also called Dance Show) team member can go from 4 to 8. <P3-S8>  A elements being worth 0.1 points, B 0.2, C 0.3, and so on until H which is worth 0.8. <P3-S9>  It originated in Europe in the 1990s, and is meant to engage children 8–18 years of age in fun individual and group exercise, free of the extremes of more strenuous aerobics or traditional gymnastics. <P3-S10>  In A category team and individual, 8 elements need to be performed (same as B category) and an acrobatic connection is optional. <P3-S11>  Skills in A category can be any difficulty. <P3-S12>  In A and B category there are duos, small groups (3-4), and big groups (5-6). <P3-S13>  There three categories (from hardest to easiest) A, B, and C, also called Dance. <P3-S14>  International competitions are organized regularly by the "International FitKid Division", in addition to national competitions.
