Why would an increase in physical capital resources lead to an increase in worker productivity?

The two most important factors contributing to increased productivity in industrialized countries in the twentieth century were:

A company produces a computer.  It pays $100 for the keyboard and outer case, $200 for the internal hardware, and $100 for the software. It sells the computer to a consumer for $500. The contribution to gross domestic product (GDP) from the sale of the computer is:

If a patient tells you repeatedly, “I really don’t know why that arm is doing that, it has a mind of its own”, what type of disorder do they have?(1pt) What should your focus of therapy be? (1pt) [Blank1]

You notice that one of your patients continually bumps into objects on his left side when propelling his wheelchair, this may be an indication on which perceptual disorder? [Blank1]

Match the following terms with their definitions. Each answer should only be used once.

If the therapist gives instructions to the patient during a therapuetic activity including “step over the line, sit next to me, go behind the mat”, what disorder do you think the patient has?(1pt) What type of treatment approach is this demonstrating? [Blank1]

Which of the following represents the stable matching produced by the Gale-Shapley algorithm when Group P makes the proposals?  

Consider three students (A, B, C) matching with three mentors (X, Y, Z). Their preference lists are as follows: Students (Group P): A: Y, X, Z B: X, Y, Z C: X, Z, Y Mentors (Group R): X: B, C, A Y: C, A, B Z: A, B, C Current Matching M: (A, Z) (B, Y) (C, X) Question: Which of the following pairs is unstable with respect to the matching M?

To prove stability, we consider a pair p-r NOT matched in M. If p never proposed to r, what can we conclude?
