In specialization hierarchies with multiple levels of supertype and subtypes, a lower-level subtype can inherit only a few of the attributes and relationships from its upper-level supertypes. a. true. b. false.

False

Explanation:

Specialization is the top-down process of identifying lower-level, more specific entity subtypes from a higher-level entity supertype.

An entity supertype is a generic entity type that is related to one or more entity subtypes.

Entity supertypes and subtypes are organized in a specialization hierarchy.

Entity subtypes do inherit many of the relationships in which the supertype entity participates.

An entity supertype can have disjoint or overlapping entity subtypes.

we can all learn from our past mistakes because we all have different ways of learning different types of techniques. my way may or may not another classmate remember and have the repetition to acknowledge such standard. such as remembering acronyms. using abbreviations to us remember keep things in order in our memory. this us figure out what comes next in the sequence. if so, what we have is a sentence of just letters all in caps. we either know the meaning or have no idea what it stands for. most of the time we know the meaning and context. but most of us who don't know, should learn by having a quick glance at what needs to be remembered. such as repetition in the memory for acronyms. one way that me, is the fact that i'm always doing math and english assignments. so we have to remember specific meanings such as soapstone for documents, such as citing correctly. or pemdas for doing the equations correctly, even if it's the super long way. this works for everyone. you just have to find what works for you by practicing and repetition daily.
