Which of the following is/are valid reason(s) for the need of MapReduce? a) In supporting parallel and distributed computing, MapReduce provides an abstraction that hides many system-level details from the programmer. b) In MapReduce, developer can focus on what computations need to be performed, as opposed to how those computations are actually carried out or how to get the data to the processes that depend on them. c) Reduce the coding size d) Mapping code to code e) Map the fastest route to destination and reduce the size of RAM 10.

Which of the following statement(s) is/are TRUE about MapReduce's functional languages? a) A key feature of functional languages is the concept of higher-order functions, or functions that can accept other functions as arguments. b) Two common built-in higher order functions are map and fold, which are used in combination c) Given a list, map takes a functionfas an argument and applies f to all elements in a list. (The function takes a single argument.) d) The application of function to each item in a list (or more generally, to elements in a large dataset) can be parallelized, e) None of the above
