Input: Article: The system was later extended to cover larger ranges and some of its practical shortcomings were addressed by the Austrian scientist Josef Maria Eder (18551944) and Flemish-born botanist Walter Hecht (de) (18961960), (who, in 1919/1920, jointly developed their EderHecht neutral wedge sensitometer measuring emulsion speeds in EderHecht grades). Still, it remained difficult for manufactures to reliably determine film speeds, often only by comparing with competing products, so that an increasing number of modified semi-Scheiner-based systems started to spread, which no longer followed Scheiner's original procedures and thereby defeated the idea of comparability.

Now answer this question: What eliminated comparability?

Output: modified semi-Scheiner-based systems

Input: Article: Gandhi Smriti in New Delhi is the location where Mahatma Gandhi spent the last 144 days of his life and was assassinated on 30 January 1948. Rajghat is the place where Mahatma Gandhi was cremated on 31 January 1948 after his assassination and his ashes were buried and make it a final resting place beside the sanctity of the Yamuna River. The Raj Ghat in the shape of large square platform with black marble was designed by architect Vanu Bhuta.

Now answer this question: On which date was Mahatma Gandhi killed?

Output: 30 January 1948

Input: Article: Throughout the universe, hydrogen is mostly found in the atomic and plasma states whose properties are quite different from molecular hydrogen. As a plasma, hydrogen's electron and proton are not bound together, resulting in very high electrical conductivity and high emissivity (producing the light from the Sun and other stars). The charged particles are highly influenced by magnetic and electric fields. For example, in the solar wind they interact with the Earth's magnetosphere giving rise to Birkeland currents and the aurora. Hydrogen is found in the neutral atomic state in the interstellar medium. The large amount of neutral hydrogen found in the damped Lyman-alpha systems is thought to dominate the cosmological baryonic density of the Universe up to redshift z=4.

Now answer this question: in the interstellar medium, what state is hydrogen in?

Output:
neutral atomic state
