Correct Answer: A. there are many buyers and few sellers

Correct Answer: B. Phenolphthalein

Explanation

Phenolphthalein is a common laboratory indicator used to detect the presence of bases in a solution. In its basic form (pH > 8.3), it turns pink or purple, indicating the presence of a base.

Explanation

(a)

(i) In the diagram,

\(x° + 90° = (3x + 15)°\) (Sum of opposite interior angles)

Thus, \(90° - 15° = 3x - x \implies 75° = 2x\)

\(x = 37.5°\)

(ii)

< RSQ = 90° - 37.5° = 52.5°

(b) \(2N4_{seven} = 15N_{nine}\)

\(2N4_{seven} = (2 \times 7^{2}) + (N \times 7^{1}) + (4 \times 7^{0})\)

= \(98 + 7N + 4\)

= \(102 + 7N\)

\(15N_{nine} = (1 \times 9^{2}) + (5 \times 9^{1}) + (N \times 9^{0})\)

= \(81 + 45 + N\)

= \(126 + N\)

\(\implies 102 + 7N = 126 + N\)

\(7N - N = 126 - 102 = 24\)

\(6N = 24 \implies N = 4\)

Therefore, \(244_{seven} = 154_{nine}\).

Correct Answer: A. influence policies of government

Correct Answer: C. legal monopoly

Correct Answer: B) limited partnership

Explanation

Now, let's look at the options again. A limited liability company, as the name suggests, offers limited liability to its owners. This means that the owners' personal assets are protected, and they are not personally responsible for the company's debts. So, option A is not the correct answer.

Option B, limited partnership, is the correct answer. In a limited partnership, there are two types of partners: general partners and limited partners. General partners have unlimited liability, which means they are personally responsible for the partnership's debts. On the other hand, limited partners have limited liability, meaning their personal assets are protected, and they are not personally responsible for the partnership's debts.

Option C, public enterprises, typically refers to government-owned businesses. These businesses may have different structures and liability arrangements, but they generally do not have unlimited liability for their members.

Option D, normal partnership, usually refers to a general partnership where all partners have unlimited liability. However, the question specifically asks for a business that must have at least one member with unlimited liability, so we cannot say for certain if this option is correct or not.

In conclusion, the correct answer is option B, limited partnership, as it is a type of business where at least one member has unlimited liability

Explanation

(a) Nehemiah, a captive in Babylon was visited by Hanai. Nehemiah wanted to know the state of Jerusalem and her inhabitants. Nehemiah was told that the remnants of the land were in great trouble and shame. He was told that the gates and the walls were broken down and destroyed. This made Nehemiah sad and he wept bitterly. He then fasted and prayed for several days. He requested for his freedom from the king of Babylon. He was allowed to go. On his arrival in Jerusalem, he delivered the king's letters to the governors of the provinces. In the letters, it was written that the materials needed by Nehemiah for the reconstruction of the city be supplied to him. This was done and the reconstruction work on the walls of Jerusalem began in earnest. Nehemiah went in the night to inspect the walls of Jerusalem that were broken down. Nehemiah said: " Let us build the walls of Jerusalem so that we may no longer suffer disgrace". The people responded and the work started, but, Samballat and. Tobiah opposed the reconstruction work.

(iii) Nehemiah's faith in God was demonstrated through prayer.

Correct Answer: C) Real accounts

Correct Answer: D. should be sure of whatever they say

Explanation

(a)(i) Upper Course:V-shaped valleys/narrow valleys, swift flowing river, vertical corrosion and river capture. Presence of cataracts, waterfalls, interlocking spurs, plunge pools and gorges

(ii) Middle Course: Wide V-shaped valleys, lateral corrosion and good for transportation. Presence of bluffs, river cliffs, meanders, terraces and some deposition take place

(iii) Lower Course:Lateral corrosion continues with deposition, meander, braiding and levee. Presence of flood plains, increase in volume of water, Ox-bow lakes, deferred confluence, delta and terraces.

(b) Importance of rivers to man:

(i) Transportation of goods and people

(ii) Generation of H. E. P

(iii) Water for domestic use

(iv) Water for industrial use

(v) Water for irrigation

(vi) Fishery

(vii) Sports

(viii) Tourism

(ix) Water for animal use

(x) Natural boundaries

(xi) Flood plains provide rich agricultural land.
