Use /etc/security/limits.conf file to limit amount of concurrent logins for a specific user.
Use the /etc/security/limits.conf record to restrict aid use for all packages. That is from the pam_limits module of the Plugable Authentication Modules (PAM) module set. Entries in /etc/security/limits.conf comprise the subsequent: Entity type limit value.
A pluggable authentication module (PAM) is a mechanism to combine multiple low-level authentication schemes right into an excessive-stage Application programming interface (API). PAM allows applications that depend on authentication to be written independently of the underlying authentication scheme.
A module is a software program component or a part of an application that includes one or greater routines. One or more independently developed modules make up an application. A company-level software application may contain numerous one-of-a-kind modules, and each module serves unique and separate business operations.

Answer: (E) none of the other choices
Explanation:
None of the options are correct in the above question.
The USA extends Most Favoured Nation Status to most countries in the world including Germany so that would not be a reason for the car's not to pass through customs.
The cars could indeed be a threat to national security. Just because they come from a safe country does not mean that they were not tampered with. They need to be properly inspected.
They are indeed a source of competition for US automakers but that would be no reason to stop them. Perhaps tariffs could be applied on them but they will not be stopped.
There is no provision in US Customs practices that prohibits the importation of used cars solely because they are used cars therefore it will not be a reason to halt the car's going through customs.
None of the options are therefore correct.

Explanation:</h3><h3>Part (a):</h3>
Solved part is attached as an image.
<h3>
Part (b):</h3>
Let us first determine the amount required of each item to produce 1 bracket.
From the attached diagram, we can see that to manufacture 1 bracket, quantity of each item needed is,
Base = 1
Spring = 2
Clamp = 1 + 4 = 5
Housing = 2
Handle = (1 * 1) + (4 * 1) = 5
Casting = (1 * 1) + (4 * 1) = 5
Bearing = 2 * 2 = 4
Shaft = 2 * 1 = 2
Hence, for 50 Brackets, quantity of each item required will be,
Base = 1 * 50 = 50
Spring = 2 * 50 = 100
Clamp = 5 * 50 = 250
Housing = 2 * 50 = 100
Handle = 5 * 50 = 250
Casting = 5 * 50 = 250
Bearing = 4 * 50 = 200
Shaft = 2 * 50 = 100
<em>NOTE: The above quantities give exclusive quantities required for each item. In actual practice, we won't have to purchase base, clamp & housing separately as the will be assembled from their components which are already procured.</em>
<h3>Part (c):</h3>
As 25 bases are already in stock, parts for them will not be needed. I will refer the quantities subtracted due to this by indicating (B). Similarly, quantities subtracted due to clamps will be indicated as (C).
Base = 50 - 25 = 25
Spring = 50
Clamp = 250 - 100 - 25(B) = 125
Housing = 100 - (2*25)(B) = 50
Handle = 1 * 125 = 125
Casting = 1 * 125 = 125
Bearing = 2 * 50 = 100
Shaft = 1 * 50 = 50
