2a)
The aim of the experiment is to determine the capillary rise of water in dry sand, dry clay, and dry loam.

(2b)
E: Least rise
F: Moderate rise
G: Highest rise

(2c)
(PICK TWO ONLY)
(i) The rise is influenced by soil type.
(ii) Loam has the highest capillary rise due to its texture.
(iii) Clay exhibits moderate capillary action.
(iv) Sand shows the least capillary rise.
(v) Soil particle size affects capillary action.
(vi) Water retention varies with soil composition.

(2d)
(PICK ONE ONLY)
(i) Prevents soil particles from escaping.
(ii) Acts as a barrier to maintain separation.
(iii) Facilitates water absorption evenly.
(iv) Maintains consistency in the experiment setup.
(v) Absorbs excess water to avoid spillage.

(2ei)
The soil in the capillary tube labelled E is best for agriculture.

(2eii)
(PICK TWO ONLY)
(i) Good drainage properties that prevent waterlogging and allow for proper aeration of plant roots.
(ii) High permeability that allows roots to easily penetrate the soil for nutrient uptake.
(iii) Low water retention which helps prevent root rot in plants.
(iv) Easy cultivation and good soil structure for root growth.
(v) Suitable for crops that require well-drained soil conditions.
(vi) Less prone to compaction, promoting healthy root development.

(4a)
