Answer:
dog
Explanation:
The python program has four lists, A, B, C, and E which is a list of the first three lists. Lists are unordered indexed data structures, it is accessed by an index starting from 0 to n (which is the length of the list minus one).
The E list is a list of lists with three list items starting from index zero to two. E[0][1] is used to access the item "dog" in the first list item of the E list.

Explanation:
All the pirates uses their individual key and lock for the locking down of each the four sides of the lid of to the chest. Among the pirates, if three of them decides to open their latches, they can be able to lift the top by essentially using the fourth (locked) latch as a hinge to open the top. (We have several solutions or ways to do this.)
Answer:
2. A data modelling project using a packaged data model REQUIRES A GREATER SKILL than a project not using a packaged data model.
Explanation:
1a. Review of universal models:
A data model is an abstract model that organizes elements of data and standardizes how they relate to one another and to the properties of real world entities. It has become the standard approach used towards designing databases.
A universal data model is a template data model that can be reused as a starting point or a building block to jump-start development of a data modelling project, industry specific model, logical data models.
1b. Discuss how these are being used more widely today.
*Universal data models helps professional reduce development time, improve consistency and standardization while achieving high quality models.
*Higher quality: just as architects consider blue prints before constructing a building, one should also consider data before building an app. A data model helps define the problem, enabling one to consider different approaches and choose best ones.
*By properly modelling and organization's data, the database designer can eliminate data redundancies (needless repetitions) which are a key source for inaccurate information and ineffective systems.
2. Greater and advanced skills are adequate and required when data modelling project is done using packaged data model while fewer skills are required when data modelling is done without packaged data model.
You can go to their house and talk to them
Kinda of both. The processor, memory, hard drive and displays are all standard components and are provided by a variety computer competent manufacturers (except for the processors which are all supplied by Intel). Yet - while many components are standard - NO, the core, hardware components, like logic boards (motherboard), video cards, and other specialty components (some display connectors and displays, for example) are propriety Apple designs.
