There are three types of hazards we discuss in the context of pipelined MIPS processor instructions executing. 1. What are the three types of hazards discussed in the book? Briefly differentiate each hazard. 2. Identify at least two different MIPS processor architectural design/implementation decisions that help us avoid or mitigate structural hazards. For each, explain why it helps address structural hazards.

Which of the following statements is false? a. a class can directly inherit from class object. b. if the class you're inheriting from declares instance variables as private, the inherited class can access those instance variables directly. c. a class's instance variables are normally declared private to enforce good software engineering. d. it's often much more efficient to create a class by inheriting from a similar class than to create the class by writing every line of code the new class requires.
