The USA PATRIOT Act of October 2001 dramatically reduces restrictions on law enforcement agencies' ability to search telephone, e-mail communications, medical, financial, and other records; eases restrictions on foreign intelligence gathering within the United States; expands the Secretary of the Treasury's authority to regulate financial transactions, particularly those involving foreign individuals and entities; and broadens the discretion of law enforcement and immigration authorities in detaining and deporting immigrants suspected of terrorism-related acts. The act also expanded the definition of terrorism to include domestic terrorism, thus enlarging the number of activities to which the USA PATRIOT Act's expanded law enforcement powers could be applied. A new Terrorist Finance Tracking Program monitored the movements of terrorists' financial resources (discontinued after being revealed by The New York Times). Global telecommunication usage, including those with no links to terrorism, is being collected and monitored through the NSA electronic surveillance program. The Patriot Act is still in effect.
If it is possible to answer this question, answer it for me (else, reply "unanswerable"): When was the Patriot Act passed?
Ah, so.. October 2001

Many, if not most, birds migrate in flocks. For larger birds, flying in flocks reduces the energy cost. Geese in a V-formation may conserve 1220% of the energy they would need to fly alone. Red knots Calidris canutus and dunlins Calidris alpina were found in radar studies to fly 5 km/h (3.1 mph) faster in flocks than when they were flying alone.
If it is possible to answer this question, answer it for me (else, reply "unanswerable"): How much faster do Red knots and dunlins fly in a flock?
Ah, so.. 3.1 mph

Another theory describes its derivation from a non-Slavic warrior class,:42, 6466 forming a distinct element known as the Lechici/Lekhi (Lechitow):430 :482 within the ancient Polonic tribal groupings (Indo-European caste systems). This hypothesis states this upper class was not of Slavonic extraction:482 and was of a different origin than the Slavonic peasants (kmiecie; Latin: cmethones):430 :118 over which they ruled.:482 The Szlachta were differentiated from the rural population. The nobleman's sense of distinction led to practices that in later periods would be characterized as racism.:233 The Szlachta were noble in the Aryan sense -- "noble" in contrast to the people over whom they ruled after coming into contact with them.:482 The szlachta traced their descent from Lech/Lekh, who probably founded the Polish kingdom in about the fifth century.:482 Lechia was the name of Poland in antiquity, and the szlachta's own name for themselves was Lechici/Lekhi.:482 An exact counterpart of Szlachta society was the Meerassee system of tenure of southern Indiaan aristocracy of equalitysettled as conquerors among a separate race.:484 The Polish state paralleled the Roman Empire in that full rights of citizenship were limited to the szlachta. The szlachta were a caste, a military caste, as in Hindu society.
If it is possible to answer this question, answer it for me (else, reply "unanswerable"): WHen did they find the polish kingdom?
Ah, so..
about the fifth century.
