Student A:Ruthenium is a chemical element with symbol Ru and atomic number 44. It is a rare transition metal belonging to the platinum group of the periodic table. Like the other metals of the platinum group, ruthenium is inert to most other chemicals. The Russian-born scientist of Baltic-German ancestry and a member of the Russian Academy of Science Karl Ernst Claus discovered the element in 1844 at Kazan State University in Russia and named it after the Latin name of his homeland, Rus. Ruthenium is usually found as a minor component of platinum ores; the annual production is about 20 tonnes. Most ruthenium produced is used in wear-resistant electrical contacts and thick-film resistors. A minor application for ruthenium is in platinum alloys and as a chemistry catalyst.

Answer this question based on the passage: where is ruthenium found on the periodic table?
Student B:OK... To answer the above question, the relevant sentence is: It is a rare transition metal belonging to the platinum group of the periodic table.
the platinum group.

Student A:The lunar south pole is located on the center base of the far side of the moon (80 S to 90 S) and covers a distance of about 1250 km. The lunar south pole has shifted 5 degrees from where it previously was billions of years ago. This shift has changed the rotational axis of the moon allowing sunlight to reach areas of the moon previously shadowed. The axis spin is 88.5 degrees from the plane of the elliptic. The south pole contains areas of permanent darkness, where the sunlight never reaches. On the contrary, the pole also contains areas with permanent exposure to sunlight. The south pole contains many craters and basins such as the South Pole-Aitken basin; which appears to be one of the most fundamental features of the moon. The south pole contains mountains such as Epsilon Peak which is taller than any mountain found on earth. The south pole is thermally benign, ranging at an average of 250 -- 270 kelvins.

Answer this question: what are the coordinates for the south pole of the moon?
Student B:
OK... To answer the above question, the relevant sentence is: The lunar south pole is located on the center base of the far side of the moon (80 S to 90 S) and covers a distance of about 1250 km.
80 S to 90 S.
