Question: However, asymmetry of causation can be observed in a non-arbitrary way which is not metaphysical in the case of a human hand dropping a cup of water which smashes into fragments on a hard floor, spilling the liquid. In this order, the causes of the resultant pattern of cup fragments and water spill is easily attributable in terms of the trajectory of the cup, irregularities in its structure, angle of its impact on the floor, etc. However, applying the same event in reverse, it is difficult to explain why the various pieces of the cup should fly up into the human hand and reassemble precisely into the shape of a cup, or why the water should position itself entirely within the cup. The causes of the resultant structure and shape of the cup and the encapsulation of the water by the hand within the cup are not easily attributable, as neither hand nor floor can achieve such formations of the cup or water. This asymmetry is perceivable on account of two features: i) the relationship between the agent capacities of the human hand (i.e., what it is and is not capable of and what it is for) and non-animal agency (i.e., what floors are and are not capable of and what they are for) and ii) that the pieces of cup came to possess exactly the nature and number of those of a cup before assembling. In short, such asymmetry is attributable to the relationship between temporal direction on the one hand and the implications of form and functional capacity on the other.
Is there an answer to this question: What else, besides direction, is asymmetry attributable to?

Answer: implications of form and functional capacity


Question: Since the Carnation Revolution of 1974, which culminated in the end of one of Portugal's most notable phases of economic expansion (that started in the 1960s), a significant change has occurred in the nation's annual economic growth.[citation needed] After the turmoil of the 1974 revolution and the PREC period, Portugal tried to adapt to a changing modern global economy, a process that continues in 2013. Since the 1990s, Portugal's public consumption-based economic development model has been slowly changing to a system that is focused on exports, private investment and the development of the high-tech sector. Consequently, business services have overtaken more traditional industries such as textiles, clothing, footwear and cork (Portugal is the world's leading cork producer), wood products and beverages.
Is there an answer to this question: Since the 90's, how has Portugal's economic development model been changing?

Answer: changing to a system that is focused on exports, private investment and the development of the high-tech sector


Question: David Archuleta's performance of John Lennon's "Imagine" was considered by many as one of the best of the season. Jennifer Lopez, who was brought in as a judge in season ten, called it a beautiful song-moment that she will never forget. Jason Castro's semi-final performance of "Hallelujah" also received considerable attention, and it propelled Jeff Buckley's version of the song to the top of the Billboard digital song chart. This was the first season in which contestants' recordings were released onto iTunes after their performances, and although sales information was not released so as not to prejudice the contest, leaked information indicated that contestants' songs frequently reached the top of iTunes sales charts.
Is there an answer to this question: For the first time, recordings of the contestant's songs could be purchased where?

Answer: iTunes


Question: Although not yet tested as a therapy in humans, a growing body of evidence indicates that zinc may preferentially kill prostate cancer cells. Because zinc naturally homes to the prostate and because the prostate is accessible with relatively non-invasive procedures, its potential as a chemotherapeutic agent in this type of cancer has shown promise. However, other studies have demonstrated that chronic use of zinc supplements in excess of the recommended dosage may actually increase the chance of developing prostate cancer, also likely due to the natural buildup of this heavy metal in the prostate.
Is there an answer to this question: What could overuse of zinc possibly cause?

Answer:
prostate cancer
