Correct Answer: B. broken

Explanation

a. After the Israelites returned from the Babylonian exile with the permission of King Cyrus to rebuild the temple in Jerusalem, they faced opposition from the Samaritans. The Samaritans approached the returning exiles with an offer to participate in the construction of the temple. However, their motives were not entirely sincere, as there was a history of animosity and religious differences between the Jews and the Samaritans.

The leaders of the returning Jewish exiles, including Zerubbabel and Jeshua, declined the Samaritans' offer to participate in the construction of the temple. They stated that they would build the temple on their own. The Samaritans did not take this rejection well. They became adversaries of the Jews and actively sought to undermine the rebuilding efforts. They engaged in efforts to frustrate and discourage the Jewish community, both through political means and by spreading false accusations against the Jews.

During the reign of Artaxerxes (successor to Ahasuerus), Rehum, a high official, and his associates wrote a letter to the king, expressing concern about the reconstruction activities in Jerusalem. The letter accused the Jews of planning to rebel against the king once the city and walls were rebuilt. The letter also cited the historical rebelliousness of Jerusalem and its potential threat to the Persian Empire.

In response to Rehum's letter, Artaxerxes issued a decree to halt the construction of the city and the temple in Jerusalem. This decree ordered a thorough investigation into the matter and instructed that the building activities cease until further notice. It was not until the reign of King Darius of Persia that the construction received official support again. The prophets Haggai and Zechariah played significant roles in encouraging the people to resume the construction, which eventually led to the completion of the temple.

The events in Ezra highlight the challenges and opposition faced by the returning Jewish exiles as they sought to rebuild the temple in Jerusalem. The Samaritans' initial offer to join in the construction turned out to be insincere, leading to a period of conflict and interruption in the rebuilding process.

b. The following are four possible causes of tension among neighbours:

1.Religious and Cultural Differences: Different beliefs, practices, and historical animosities can create tensions among neighbours. The rejection by the Jewish leaders of the Samaritans' offer to participate in the temple construction could be rooted in religious and cultural differences.

2.Historical Grievances and Mistrust:Past conflicts or perceived injustices can linger and contribute to ongoing tensions between neighbouring communities. The Samaritans' opposition to the Jews may have been influenced by historical grievances and mistrust.

3.Competition for Resources:Competition for resources, whether economic or symbolic, can lead to tensions among neighbours. The Samaritans' desire to join in the construction of the temple could have been driven by a strategic interest in sharing the benefits or resources associated with the temple.

4.Political and Power Dynamics:Political ambitions, power struggles, and the fear of potential rebellion can create tension among neighboring regions, especially when there is a perceived threat to the ruling authority. The involvement of high officials like Rehum and his associates in writing to Artaxerxes suggests a political dimension to the tensions.

Correct Answer: C. cash

Explanation

Liquidity refers to how easily an asset can be converted into cash without loss of value. Cash is the most liquid asset because it can be used to purchase goods and services immediately. Shares, bonds, and cheques are less liquid because they cannot be converted into cash as easily.

Correct Answer: B) whole house of Israel

Explanation

In the book of Ezekiel in the Bible, the prophet Ezekiel speaks about dry bones in a vision he had. In this vision, Ezekiel is taken to a valley that is full of bones, which represent the whole house of Israel. The bones are described as being very dry, which means that they have been there for a long time and are lifeless.

God commands Ezekiel to prophesy to the bones, telling them to hear the word of the Lord. As Ezekiel speaks, the bones begin to come together and are covered with flesh and skin. Then, God breathes life into the bodies and they come to life, standing on their feet as a vast army.

Therefore, the correct option is B: whole house of Israel. The dry bones mentioned by Prophet Ezekiel in the statement refer to the whole house of Israel who had lost hope and were lifeless. Through this vision, God shows Ezekiel that He has the power to restore life to what was once dead.

Correct Answer: B. 1

Correct Answer: B. load and the radius of the wire

Correct Answer: D. personal and impersonal account

Explanation

(a)(i) A machine is a device in which an effort applied at one end is used to overcome a load at another point. Machine makes work easier.

(ii) Uses of gears are: - to change speed to change direction of motion

- to magnify force.

(iii) Velocity ratio of a gear wheel is the ratio of number of teeth on driven wheel to number of teeth on driving wheel OR

Velocity ratio = \(\frac{\text{Time rate of revolution/speed/radius of driven wheel}}{\text{Time rate of revolution/speed/radius of driving wheel}}\)

(iv) To increase the mechanical advantage, the driving gear is made smaller with fewer teeth than the driven gear.

(b) Number of teeth on driven gear = 12.

Number of teeth on driving gear = 18.

(i) V.R. = \(\frac{\text{no. of teeth on driven gear}}{\text{no. of teeth on driving gear}}\)

= \(\frac{12}{8} = \frac{2}{3}\)

(ii) Efficiency - \(\frac{M.A}{V.R}\) x 100% = x 100%

= \(\frac{L/E}{V.R}\) x 100%

90 = \(\frac{70/E}{2/3}\) x 100%

(iii) This is due to: - Friction between the tyres and load.

- Friction between chain and gear.

(ii) Scale of preference The list of unsatisfied wants arranged in order of priority

(b) Reasons why agricultural insurance is important

- Guarantees farmer's income against losses due to natural disaster

- Save guards against failure/collapse of farm business enterprises/ Encourages farmers to plant for the future

- Attracts investors to agricultural business/encourages commercial farming/ encourage agricultural development

- Improves farmer's standard of living

- Facilitates access to farm credit

(c) Fishery regulations in West Africa

- Ban on the use of toxic chemicals/poisons

- Landing tax is paid based on the total catch and sizes of fish at landing sites

- Fishing areas are allocated to individual fishermen so as to curb indiscriminate interference within the large fishing areas

- No vessels (except canoes) shall fish within the first two nautical miles of the territorial waters a country's continental shelf

- No person shall operate or navigate any motorised fishing boat within the territorial water of other country unless a license in respect of that vessel has been issued

- Identified breeding section of water is normally restricted from fishing

- Fishing activities is restricted during rainy season/ close season regulation

- The use of prescribed/particular/restricted mesh size in fishing to protect young fish

- Ban on the discharge of pollutants or toxic materials into a country's terririal water

- Ban on the use of explosives in fishing except for the purpose of research

- Ban on the use of electric fishing except for the purpose of research

- Coastal areas to be constantly under surveillance to restrict foreign vessels from exploitation

- certification that fishes to be sold to the public are free from all toxic substances and human consumption must be obtained

- Exportation of fish products shall be done through the normal procedures not from the sea

- There should be regular stocking of a compatible species in order to increase the population of fishes in the water

- A fisherman is only alowed to catch a specific quantity of fish at a particular time

(d) Reasons why beekeeping is important

- Source of honey used as food/medicine

- Source of propollis/ venom used as medicine

- Source of income
