Regarding to the following B+Tree(m=4), If we delete index keys = all 4s, all 2s, and insert 6 what is the B+Tree index after the operations?  Note: Please show each step for deletion, not only the final answer.                                                                               

CAP Theorem.  Please provide the scenario and describe how the scenario relates to C-P in CAP Theorem. 

There are four relations as follows: Student (id(PK), name, dept_name(FK), gpa, major, phone, advisor_name) Department (dept_name(PK), building, budget) Takes (id(PK, FK), course_id(PK, FK), sec_id(PK, FK), semester(PK, FK), year(PK, FK) , grade) Course (course_id(PK), title, dept_name(FK), credit_hours) Note.  PK = Primary key, and FK = Foreign key. Given: the number of records in table Student = 1,000.              the number of records in table Course = 100.              the number of records in table Takes = 5,000.              the number of records in table Department = 10.   Given Query:  Find the name, phone, and gpa of students are in “CS” department and took the course’s title “Introduction to Biology” in Fall 2024 which is offered by “Biology” department and earned “A” grade.            A.) Create the SQL Command for this query.                                                                              (3 Points)         B.) According to A.) what is the relational algebra expression for the SQL command?         (3 Points)         C.) According to B.) what is the optimize relational expression tree?                                      (4 Points)

Solving a problem via insight has a unique characteristic not associated with other problem solving processes. What is that characteristic?

Some researchers argue for the role of theory and knowledge in the structure of people’s concepts. These researchers demonstrate that:

When children say that a toy monkey is more similar to a person than is a real worm, but also say that a real worm is more likely to have a spleen (given that people have a spleen) than is a toy monkey, those children are
