Input: Consider Input: Question: Is serpentine blue like Boron? Passage:The earliest recorded blue diamond, the Hope Diamond, was discovered in India, in the Kollur mine in the Guntur district of Andhra Pradesh (which at the time was part of the Golconda kingdom), in the seventeenth century. However, blue diamonds have also been discovered in the Cullinan Mine in South Africa and the Golconda region. A few blue diamonds have been discovered in the Argyle Mine in Western Australia as well, and are offered at their annual Argyle Tender when they are found. It is thought that blue diamonds, unlike most other diamonds, are formed in the lower part of Earth’s mantle, and that the boron creating their blue color originates from serpentinite carried down to the mantle by subducting ocean tectonic plates.

Input: Consider Input: Question: Who first established the organization whose headquarters are at 85 Stone Nullah Lane? Passage:From its southern end, Stone Nullah Lane begins at its junction with Lung On Street. This is where the Wan Chai Pak Tai Temple is located. Made from grey-coloured brick and granite, it was constructed in 1863, although the statue of Pak Tai inside dates even further back to 1604. The temple is the oldest in the district, and reportedly the largest on Hong Kong Island. The next landmark on the route is the headquarters of St. James' Settlement. Situated at 85 Stone Nullah Lane, the charitable organisation was established here in 1949 with the goal of helping impoverished children living in squats around the neighbourhood, and now extends its services to needy people across the city. The current structure towers 12-storeys above the lane. Before the street turns onto Queen's Road East and ends, it passes the Blue House, a Grade I historic building. The building—whose Spanish balconies made from cast-iron have elicited comparisons to ones in New Orleans—was built in the 1920s and was originally utilised as a health centre for the community, a school teaching kung fu from the 1950s to 1960s, and now houses a museum.
