(1a) A ranging pole is a sturdy, highly visible pole used in surveying and construction to mark positions and establish sight lines. Typically made from wood or metal, these poles are painted in alternating red and white or black and white bands to ensure visibility over long distances. They usually measure 2-3 meters in length and may have a pointed end for easy placement in the ground.

(i) Spec A: Ranging Pole – used to establish sight lines and mark positions during surveying.
(ii) Spec B: Arrow – a small metal pin used to mark measurement points on the ground.
(iii) Spec C: Measuring Tape – a flexible ruler used to measure distances or sizes.
(iv) Spec D: Wooden Peg – used to permanently mark surveyed land boundaries.

To test for the capillary actio of water in different soil samples
(2b)
Spec E; it has lowest capillarity
Spec F; it has the highest capillarity
Spec G; the capillarity is moderate
(2c)
(i)soil sample E has the least capillarity due to it coarse and fine nature therefore it is a sandy soil
(ii) Soil sample F has the highest capillarity action therefore it is a clay soil
