Q: An own goal is an event in competitive goal-scoring sports (such as association football or basketball) where a player scores on their own side of the playing area rather than the one defended by the opponent. Own goals sometimes result from the opponent's defensive strength, as when the player is stopped in the scoring area, but can also happen by accident. Since own goals are often added to the opponent's score, they are often an embarrassing blunder for the scoring player, but in certain sports are occasionally done for strategic reasons.
Can we conclude that can you score an own goal in basketball?

The use of toxic chemicals as weapons dates back thousands of years, but the first large scale use of chemical weapons was during World War I. They were primarily used to demoralize, injure, and kill entrenched defenders, against whom the indiscriminate and generally very slow-moving or static nature of gas clouds would be most effective. The types of weapons employed ranged from disabling chemicals, such as tear gas, to lethal agents like phosgene, chlorine, and mustard gas. This chemical warfare was a major component of the first global war and first total war of the 20th century. The killing capacity of gas was limited, with about ninety thousand fatalities from a total of 1.3 million casualties caused by gas attacks. Gas was unlike most other weapons of the period because it was possible to develop countermeasures, such as gas masks. In the later stages of the war, as the use of gas increased, its overall effectiveness diminished. The widespread use of these agents of chemical warfare, and wartime advances in the composition of high explosives, gave rise to an occasionally expressed view of World War I as ''the chemist's war'' and also the era where weapons of mass destruction were created.

Interstitial fluid consists of a water solvent containing sugars, salts, fatty acids, amino acids, coenzymes, hormones, neurotransmitters, white blood cells and cell waste-products. This solution accounts for 26% of the water in the human body. The composition of interstitial fluid depends upon the exchanges between the cells in the biological tissue and the blood. This means that tissue fluid has a different composition in different tissues and in different areas of the body.

OPTIONS:
- no
- yes

is the fluid component of blood a complex mixture of water?

A: yes
Problem: Text: Thanksgiving, or Thanksgiving Day, is a public holiday celebrated on the fourth Thursday of November in the United States. It originated as a harvest festival. Thanksgiving has been celebrated nationally on and off since 1789, after Congress requested a proclamation by George Washington.

IN: Is it true that can a compound be both an acid and a base?

In chemistry, an amphoteric compound is a molecule or ion that can react both as an acid as well as a base. Many metals (such as copper, zinc, tin, lead, aluminium, and beryllium) form amphoteric oxides or hydroxides. Amphoterism depends on the oxidation states of the oxide. AlO is an example of an amphoteric oxide.
