Given the question: Information:  - Star Kingdom (formerly known as Star King) (19461967) was a Thoroughbred race horse bred in Ireland in 1946. Exported to Australia he was an outstanding sire, being the leading sire for five seasons, the leading sire of two-year-olds seven times as well as heading the broodmare sires' list three times.  - Sweet Embrace was a notable Australian thoroughbred racehorse . She was a chestnut daughter of Todman from the Port Vista mare Miss Port . She was owned by Jack and Bob Ingham . She is best remembered for winning the 1967 STC Golden Slipper Stakes as a maiden at long odds of 40/1 . The Sweet Embrace Stakes run annually at Randwick Racecourse is named in her honour .  - or "cultivars" of an animal species, achieved through the process of selective breeding. When the lineage of a purebred animal is recorded, that animal is said to be "pedigreed".  - The Australian Racing Hall of Fame is part of the Australian Racing Museum which documents and honours the horseracing legends of Australia. The museum officially opened in 1981 and created the Hall of Fame in 2000.  - The Thoroughbred is a horse breed best known for its use in horse racing. Although the word "thoroughbred" is sometimes used to refer to any breed of purebred horse, it technically refers only to the Thoroughbred breed. Thoroughbreds are considered "hot-blooded" horses that are known for their agility, speed and spirit.  - Todman (7 October 1954-1976) was one of the greatest Australian Thoroughbred racehorses and an important sire. He was perhaps best known as the winner of the inaugural STC Golden Slipper in 1957, being the first of Star Kingdoms five successive winners of the race. He was inducted into the Australian Racing Hall of Fame in 2005.   - A breed is a specific group of domestic animals having homogeneous appearance (phenotype), homogeneous behavior, and/or other characteristics that distinguish it from other organisms of the same species. Breeds are formed through genetic isolation and either natural adaptation to the environment or selective breeding, or a combination of the two. Despite the centrality of the idea of "breeds" to animal husbandry and agriculture, no single, scientifically accepted definition of the term exists. A breed is therefore not an objective or biologically verifiable classification but is instead a term of art amongst groups of breeders who share a consensus around what qualities make some members of a given species members of a nameable subset.    Given the paragraphs above, decide what entity has the relation 'instance of' with 'race horse'.
The answer is:
sweet embrace
