Correct Answer: B. not hearing the word of the Lord

Correct Answer: B. profit level

Correct Answer: A. 0.00030k^-1

Explanation

Ya = \(\frac{\text{Vol. expelled}}{\text{Vol. left x temp. change}} = \frac{0.75}{49.25 \times 50}\)

= 0.00030k^-1

Correct Answer: C. was taken

Explanation

The correct answer is C. was taken.

Here's why:

1. To be taken for someone/something is an idiom meaning to be mistaken for someone/something.

* Example: She was taken for her sister. (People thought she was her sister.)

* Example: He's often taken for a movie star. (People often mistake him for a movie star.)

2. The first part of the sentence, His English was so good, is in the past tense. Therefore, the consequence should also be in the past tense.

• A. took (active voice, meaning he performed the action of taking) - Incorrect. He took for an Englishman makes no sense.

• B. is taken (present tense passive) - Incorrect tense, as the first part is past tense.

• C. was taken (past tense passive) - Correct. It uses the idiom in the correct past tense.

• D. has taken (present perfect active) - Incorrect tense and voice.

The sentence means: His English was so good that people mistook him for an Englishman.

Correct Answer: D. y = \(\frac{1}{2}x + 1\)

Explanation

y = mx + c; when x = 0; y = 1

1 = m(0) + c; 1 = 0 + c; c = 1

when x = 2; y = 2

2 = m(2) + c; 2 = 2m + c; but c = 1

2 = 2m + 1

2 - 1 = 2m

2m = 1

m = \(\frac{1}{2}\)

y = \(\frac{1}{2}\)x + 1

Calculation of the force needed to produce extension of material

F = Ke

= 988.3 x 3 x 3

= 8840.74N

Explanation

(a) Conservation of natural resources is necessary for the following reasons:

(1) The wise use/safe-keeping/ management of natural resources, for the benefit of mankind, (2) To ensure their continuous availability/avoid their decline/extinction.

(b)(i) The following are the methods of soil conservation:

(1) Planting grasses/legumes

(2) Crops must be planted on ridges across slopes

(3) Practicing shifting cultivation/bush fallowing/crop rotation

(4) Avoiding/preventing bush burning

(5) Addition of manure/fertilizer to the top soil

(6) Spreading a layer of vegetable material on cultivated farmland/mulching

(7) Constructing ridges across the slope of the land at intervals/contour ridging

(8) Planting trees/reafforestation

(9) Prevention of over-grazing

(ii) Natural resources that can be conserved are:

(1) Water

(2) Forest

(3) Wildlife

(4) Mineral resources

(5) Genetic mineral/genes

(6) Petroleum/coal/gas/fossil fuel/ iron ore, tin, gold

(c) Factors that negatively affect conservation of forest in West Africa include the following:

(1) Uncontrolled/over-exploitation of forest trees/indiscriminate felling/lumbering of forest trees

(2) Lack of afforestation/tree planting.

(3)Bush burning/wild fires

(4) Non enforcement of conservation laws

(5) Lack of /no knowledge of conservation education/awareness

(6) Use of firewood/charcoal for fuel

(7) Air/soil pollution.

(d) Denitrification stage of the nitrogen cycle: -

• Denitrifying bacteria/certain fungi in the soil
• Convert nitrates into nitrites
• Some bacteria/pseudomonas spp can convert ammonia/nitrite/nitrate into gaseous nitrogen, which is released into the atmosphere, leading to reduction of soil nitrogen content, resulting in reduced soil fertility
