Correct Answer: C. League of Nations

Explanation

The League of Nations was the first intergovernmental organization that was established after World War 1 in order to try and maintain peace. It was headquartered in Geneva, Switzerland and designed to be a forum for handling international disputes before they flared up into military action and caused domino effects that pulled ally nations into the conflict (as had happened with the Great War). Unfortunately, the League failed miserably in its intended goal: to prevent another world war from happening (WW2 broke out only two decades later). The idea was for the League of Nations to prevent wars through disarmament, collective security, and negotiation. It was also involved in other issues such as drug trafficking, arms trade, and global health. Although the League disbanded during WW2, it was replaced with the United Nations, which is still going strong today.

Correct Answer: D. Hanani

Explanation

(a) \(3y^{2} - 5y + 2 = 0\)

\(\frac{3y^{2}}{3} - \frac{5y}{3} = \frac{-2}{3}\)

\(y^{2} - \frac{5}{3}y = \frac{-2}{3}\)

\(\frac{1}{2} of \frac{-5}{3} = \frac{-5}{6}\)

\(y^{2} - \frac{5}{3}y + (-\frac{5}{6})^{2} = \frac{-2}{3} + (\frac{-5}{6})^{2}\)

\((y - (\frac{5}{6}))^{2} = \frac{1}{36}\)

Taking square root of both sides,

\(\sqrt{(y - (\frac{5}{6}))^{2}} = \sqrt{\frac{1}{36}}\)

\(y - \frac{5}{6} =\pm {\frac{1}{6}}\)

\(y = \frac{5}{6} \pm \frac{1}{6}\)

\(y = \frac{5}{6} + \frac{1}{6} = 1.00\) or \(y = \frac{5}{6} - \frac{1}{6} = \frac{2}{3} = 0.67\).

(b) \(M = \begin{pmatrix} 1 & 2 \\ 4 & 3 \end{pmatrix}, N = \begin{pmatrix} m & x \\ n & y \end{pmatrix}\)

\(MN = \begin{pmatrix} m + 2n & x + 2y \\ 4m + 2n & 4x + 2y \end{pmatrix} = \begin{pmatrix} 2 & 1 \\ 3 & 4 \end{pmatrix}\)

\(m + 2n = 2 ... (1)\)

\(4m + 2n = 3 ... (2)\)

Multiplying (1) by 4, we have

\(4m + 8n = 8 ... (3)\)

(3) - (1) : \(8n - 2n = 8 - 2 = 6\)

\(6n = 6 \implies n = 1\)

\(m + 2n = m + 2(1) = m + 2 = 2\)

\(m = 2 - 2 = 0\)

\(x + 2y = 1 ... (1)\)

\(4x + y = 4 ... (2)\)

Multiply (1) by 4,

\(4x + 8y = 4 ... (3)\)

(3) - (2) : \(8y - y = 4 - 4 = 0\)

\(\implies y = 0\)

\(x + 2y = x + 2(0) = x + 0 = 1\)

\(x = 1 - 0 = 1\)

\(\therefore N = \begin{pmatrix} 1 & 0 \\ 0 & 1 \end{pmatrix}\).

(c)Reasons why farmers keep records

• Farm records when properly kept, provide the farmer with valuable information for future budgeting and planning of the farm;
• Details of farm records are used for taxation/tax assessment;
• Farm records can enable the farmer to obtain loans from banks;
• Used for auditing the farm/farm evaluation;
• The records will enable the farmer to know whether his farm is progressing from one year to another/strengths and weaknesses of the farm/credit worthiness;
• Help to detect fraudulent practices on the farm;
• Enable farmers to compare one enterprise to another on the same farm;
• Help in decision making;
• Show the history of business transactions of the farm.
