Краткие пояснения:

• A / An употребляются с исчисляемыми существительными в единственном числе, когда предмет упоминается впервые: a bird, an umbrella, a fair, a friend.

• The употребляется, когда речь идёт об определённом, известном или единственном в данной ситуации предмете: the bush, the newspaper, the park, the train, the goal, the road.

• Без артикля употребляются некоторые слова, например наречие very в предложении 9.

• В предложении 10 используется противопоставление an enemy — a friend.

• В предложении 12 текст, по-видимому, обрывается. После cutting по смыслу должно быть указано, что именно сапожник резал. Если имеется в виду кожа, правильнее написать: cutting leather.
