Let the original cost price be 100. With 20% profit, the original selling price is 120. After a 25% increase, the new selling price is 120 × 1.25 = 150. The new profit is 25%, so the new cost price must satisfy: new cost price × 1.25 = 150, giving new cost price = 120. The increase in cost price is from 100 to 120, which is a 20% increase. However, this contradicts the options, so let's re-examine: The original profit is 20%, so SP1 = CP × 1.20. After a 25% increase in selling price, SP2 = SP1 × 1.25 = CP × 1.20 × 1.25 = CP × 1.5. The new profit is 25%, so SP2 = new CP × 1.25. Equate: new CP × 1.25 = CP × 1.5 → new CP = (CP × 1.5)/1.25 = CP × 1.2, which is a 20% increase in cost price. Therefore, the percentage increase in cost price is 20%. The correct answer is A, not B. Correction made accordingly.

Let the son's present age be x years. The father says, "I was your present age when you were born," which means the father's age at the son's birth was x years. Since the father's current age is 36, the difference between their ages is 36 - x. This difference is constant and equals the son's current age x. So, 36 - x = x, which gives 2x = 36, hence x = 18 years. Since 18 years is not among the given options, the correct choice is D (None of these).

In this sentence, 'The woman I spoke to' is correct because the relative pronoun 'who' or 'whom' can be omitted when it functions as the object of the verb in the relative clause. Option C is the most natural and grammatically correct choice.

The sentence requires a noun phrase to complete it correctly. Option A, 'Fossil fuel', fits grammatically and semantically as the subject of the sentence. Options B and C are grammatically incorrect in this context, and D is not appropriate since A is correct.

The present perfect continuous tense 'has been trying' correctly indicates an action that started in the past and continues up to the present, matching the time expression 'for the last twenty minutes.'
