The table below gives the climatic data for two different stations A & B, in Nigeria. Use the data to answer the questions that follow station Altitude Lati...

(i) Climatic belt of each station

• Station A (13°N): total rainfall 72.8 cm with a single maximum (August) and about six dry months. This is the Sudan / tropical continental (savanna) belt of the far north.
• Station B (7°N): total rainfall 123.0 cm with a double maximum (June and September) and a short August dip. This is the tropical wet / Guinea (southern) belt near the coast.

(ii) Main climatic characteristics

Station A: high temperatures with a large annual range (26 to 33°C, range 7°C, hottest just before the rains in April); a short single rainy season (June to September) and a long, marked dry season; moderate total rainfall (about 728 mm). Skies are clear for much of the year and the harmattan is strongly felt.

Station B: uniformly high temperatures with a small annual range (23 to 29°C, range 6°C); a long rainy season with two maxima (the "little dry season" showing as the August dip); high humidity and a large total (about 1230 mm). The climate is hot and wet for most of the year.

(iii) Differences in agricultural practice

• Station A (short, single wet season, drier): suited to drought-tolerant crops and grains such as millet, guinea-corn (sorghum), groundnuts, cotton and cowpeas, usually one crop per year timed to the rains; the open grassland also supports livestock rearing (cattle, sheep, goats), and irrigation is often needed.
• Station B (long, double wet season, wetter): suited to root and tree crops needing much moisture such as yam, cassava, cocoa, oil palm, plantain, rubber and kola; the two rainfall peaks allow two planting seasons a year, and the heavier rain favours arable crop farming rather than large-scale grazing (tsetse fly also limits cattle).
