(a) Three ways specimen A (radio transmitter) enhances farmers' productivity

1. It broadcasts improved farming practices and extension information to many farmers at once.
2. It gives timely weather forecasts and market price information for planning.
3. It provides early warning on pest/disease outbreaks and government agricultural programmes.

(b) Specimen B (Burdizzo plier)

(i) Operation: Castration (bloodless castration) of male farm animals.

(ii) How it is used: The animal is restrained; the spermatic cord of the testicle is located and placed within the jaws of the Burdizzo, which is then closed firmly to crush the cord without breaking the skin, cutting off blood supply to the testes. The process is repeated on the other cord.

(iii) Two maintenance practices: clean and dry it after use and oil the hinge/joint to prevent rust; keep the jaws well aligned and store in a dry place.

(c) Three uses of specimen C (basket)

1. For harvesting and collecting fruits, vegetables and other produce.
2. For conveying/storing farm produce and eggs.
3. For measuring and marketing produce, and for draining/washing produce.

(d) Importance of specimen D (egg candler)

The egg candler is used to examine eggs against a bright light (candling) to detect fertility, check for blood spots, cracks and the size of the air space, so that only good, fertile eggs are set for incubation and bad ones are removed.
