In this task, you are given Wikipedia articles on a range of topics as passages and a question from the passage. We ask you to answer the question by classifying the answer as 0 (False) or 1 (True)

Passage: Melting point -- For most substances, melting and freezing points are approximately equal. For example, the melting point and freezing point of mercury is 234.32 kelvins (−38.83 °C or −37.89 °F). However, certain substances possess differing solid-liquid transition temperatures. For example, agar melts at 85 °C (185 °F) and solidifies from 31 °C (88 °F; 304 K); such direction dependence is known as hysteresis. The melting point of ice at 1 atmosphere of pressure is very close to 0 °C (32 °F; 273 K); this is also known as the ice point. In the presence of nucleating substances, the freezing point of water is not always the same as the melting point. In the absence of nucleators water can exist as a supercooled liquid down to −48.3 °C (−55°F, 224.8 K) before freezing. The chemical element with the highest melting point is tungsten, at 3,414 °C (6,177 °F; 3,687 K); this property makes tungsten excellent for use as filaments in light bulbs. The often-cited carbon does not melt at ambient pressure but sublimes at about 3,726.85 °C (6,740.33 °F; 4,000.00 K); a liquid phase only exists above pressures of 10 MPa (99 atm) and estimated 4,030--4,430 °C (7,290--8,010 °F; 4,300--4,700 K) (see carbon phase diagram). Tantalum hafnium carbide (TaHfC) is a refractory compound with a very high melting point of 4215 K (3942 °C, 7128 °F). At the other end of the scale, helium does not freeze at all at normal pressure even at temperatures close to absolute zero; pressure greater than twenty times of atmosphere of normal one is necessary.

Passage: Mpemba effect -- The Mpemba effect is a process in which hot water can freeze faster than cold water. The phenomenon is temperature-dependent. There is disagreement about the parameters required to produce the effect and about its theoretical basis.
Question: will warm water freeze quicker than cold water

Passage: Grammy Award -- The Grammys have also been accused of being unfavorable and racist to black recording artists. Canadian artist Drake accused the awards in a 2017 interview of seeing him only as a rapper and not as a pop-music artist because of his previous work and because of his heritage. He criticized the snubbing of ``One Dance'' for the prestigious award of Record of the Year and the nomination of ``Hotline Bling'' for Best Rap Song and Best Rap/Sung Performance despite it not being a rap song. The Atlantic's Spencer Kornhaber accused the Grammys of ``sidelining a black visionary work in favor of a white traditionalist one''. Drake did not attend the 2017 Awards Ceremony where he was nominated. He had a performance in Manchester, England on February 12, 2017, the same night as the ceremony. Frank Ocean was vocal about boycotting the same Grammy Awards and did not submit his album for awards consideration as a protest.
