Problem: Please answer a question about the following article about Antenna (radio):
Reflections generally affect polarization. For radio waves, one important reflector is the ionosphere which can change the wave's polarization. Thus for signals received following reflection by the ionosphere (a skywave), a consistent polarization cannot be expected. For line-of-sight communications or ground wave propagation, horizontally or vertically polarized transmissions generally remain in about the same polarization state at the receiving location. Matching the receiving antenna's polarization to that of the transmitter can make a very substantial difference in received signal strength.
What mostly affects polarization?
A: Reflections
Problem: Please answer a question about the following article about Asthma:
Many other conditions can cause symptoms similar to those of asthma. In children, other upper airway diseases such as allergic rhinitis and sinusitis should be considered as well as other causes of airway obstruction including: foreign body aspiration, tracheal stenosis or laryngotracheomalacia, vascular rings, enlarged lymph nodes or neck masses. Bronchiolitis and other viral infections may also produce wheezing. In adults, COPD, congestive heart failure, airway masses, as well as drug-induced coughing due to ACE inhibitors should be considered. In both populations vocal cord dysfunction may present similarly.
In adults, what conditions can cause the symptoms of asthma?
A: COPD, congestive heart failure, airway masses, as well as drug-induced coughing due to ACE inhibitors
Problem: Please answer a question about the following article about Economy of Greece:
After fourteen consecutive years of economic growth, Greece went into recession in 2008. By the end of 2009, the Greek economy faced the highest budget deficit and government debt-to-GDP ratios in the EU. After several upward revisions, the 2009 budget deficit is now estimated at 15.7% of GDP. This, combined with rapidly rising debt levels (127.9% of GDP in 2009) led to a precipitous increase in borrowing costs, effectively shutting Greece out of the global financial markets and resulting in a severe economic crisis.
How many years of consecutive growth had Greece had?
A: fourteen
Problem: Please answer a question about the following article about Richmond, Virginia:
Richmond recovered quickly from the war, and by 1782 was once again a thriving city. In 1786, the Virginia Statute for Religious Freedom (drafted by Thomas Jefferson) was passed at the temporary capitol in Richmond, providing the basis for the separation of church and state, a key element in the development of the freedom of religion in the United States. A permanent home for the new government, the Virginia State Capitol building, was designed by Thomas Jefferson with the assistance of Charles-Louis Clérisseau, and was completed in 1788.
What is the Virginia Statute for Religious Freedom?
A:
the basis for the separation of church and state
