Suppose, you got a situation where you find that your linear regression model is under fitting the data. In such situation which of the following options would you consider?
1. I will add more variables
2. I will start introducing polynomial degree variables
3. I will remove some variables
Assertion (A): When there is an evidence of a linear relationship between two variables, it may not always mean an independent-dependent relationship between the two variables.
Reason (R): The casual relationship between the two variables may not imply a reasonable theoretical relationship between the two.
Consider a Simple Checkpointing Protocol and the following set of operations in the log. (start, T4); (write, T4, y, 2, 3); (start, T1); (commit, T4); (write, T1, z, 5, 7); (Checkpoint); (start, T2); (write, T2, x, 1, 9); (commit, T2); start, T3); (write, T3, z, 7, 2); if a crash happens now and the system tries to recover using both undo and redo operations, what are the contents of the undo list and the redo list?

The question below consists of a set of labelled sentences. Out of the four options given, select the most logical order of the sentences to form a coherent paragraph. P: The primary software tool used to do this is the spreadsheet. Spreadsheet language allows the financial modeller to reconstruct almost any cash flow or revenue stream. Q: A financial model tries to capture all the variables in a particular event. It then quantifies the variables and creates formulas around these variables. R: The model is usually characterised by performing calculations and makes recommendations based on that information. S: Financial modelling is the process by which a firm constructs a financial representation of some, or all, aspects of the firm or given security. 
For a statement S in a program, in the context of liveness analysis, the following sets are defined: USE(S): the set of variables used in S IN(S): the set of variables that are live at the entry of S OUT(S): the set of variables that are live at the exit of S Consider a basic block that consists of two statements, S1 followed by S2. Which one of the following statements is correct?
