Problem: Treaty:

Consent is also invalid if it is given by a representative who ignored restrictions he is subject to by his sovereign during the negotiations, if the other parties to the treaty were notified of those restrictions prior to his signing.[citation needed]

If a state's representative ignored restrictions he is subject to by his sovereign, what might that state's consent to a treaty be considered to be?
---
A: invalid


Problem: This is a consequence of Lorentz reciprocity. For an antenna element  not connected to anything (open circuited) one can write . But for an element  which is short circuited, a current is generated across that short but no voltage is allowed, so the corresponding . This is the case, for instance, with the so-called parasitic elements of a Yagi-Uda antenna where the solid rod can be viewed as a dipole antenna shorted across its feedpoint. Parasitic elements are unpowered elements that absorb and reradiate RF energy according to the induced current calculated using such a system of equations.
What element absorbs and reradiate RF-energy?
---
Answer: Parasitic


Q: What is a question about this article? If the question is unanswerable, say "unanswerable".
During most of the Neolithic age of Eurasia, people lived in small tribes composed of multiple bands or lineages. There is little scientific evidence of developed social stratification in most Neolithic societies; social stratification is more associated with the later Bronze Age. Although some late Eurasian Neolithic societies formed complex stratified chiefdoms or even states, states evolved in Eurasia only with the rise of metallurgy, and most Neolithic societies on the whole were relatively simple and egalitarian. Beyond Eurasia, however, states were formed during the local Neolithic in three areas, namely in the Preceramic Andes with the Norte Chico Civilization, Formative Mesoamerica and Ancient Hawaiʻi. However, most Neolithic societies were noticeably more hierarchical than the Paleolithic cultures that preceded them and hunter-gatherer cultures in general.
What social groups were formed during the Neolithic age of Eurasia?
A: small tribes


Context and question: IndyMac often made loans without verification of the borrower’s income or assets, and to borrowers with poor credit histories. Appraisals obtained by IndyMac on underlying collateral were often questionable as well. As an Alt-A lender, IndyMac’s business model was to offer loan products to fit the borrower’s needs, using an extensive array of risky option-adjustable-rate-mortgages (option ARMs), subprime loans, 80/20 loans, and other nontraditional products. Ultimately, loans were made to many borrowers who simply could not afford to make their payments. The thrift remained profitable only as long as it was able to sell those loans in the secondary mortgage market. IndyMac resisted efforts to regulate its involvement in those loans or tighten their issuing criteria: see the comment by Ruthann Melbourne, Chief Risk Officer, to the regulating agencies.
IndyMac gave loans to borrower's with what type credit histories?
Answer: poor


Question: A global drop in sea level at the end of the Devonian reversed early in the Carboniferous; this created the widespread epicontinental seas and carbonate deposition of the Mississippian. There was also a drop in south polar temperatures; southern Gondwana was glaciated throughout the period, though it is uncertain if the ice sheets were a holdover from the Devonian or not. These conditions apparently had little effect in the deep tropics, where lush coal swamps flourished within 30 degrees of the northernmost glaciers. A mid-Carboniferous drop in sea-level precipitated a major marine extinction, one that hit crinoids and ammonites especially hard. This sea-level drop and the associated unconformity in North America separate the Mississippian Period from the Pennsylvanian period.
Is there an answer to this question: The Pennsylvania period is separated by the drop in Carboniferous era sea levels from what other period?

Answer: Mississippian Period


In many parts of the world football evokes great passions and plays an important role in the life of individual fans, local communities, and even nations. R. Kapuscinski says that Europeans who are polite, modest, or humble fall easily into rage when playing or watching football games. The Côte d'Ivoire national football team helped secure a truce to the nation's civil war in 2006 and it helped further reduce tensions between government and rebel forces in 2007 by playing a match in the rebel capital of Bouaké, an occasion that brought both armies together peacefully for the first time. By contrast, football is widely considered to have been the final proximate cause for the Football War in June 1969 between El Salvador and Honduras. The sport also exacerbated tensions at the beginning of the Yugoslav Wars of the 1990s, when a match between Dinamo Zagreb and Red Star Belgrade degenerated into rioting in May 1990.
If it is possible to answer this question, answer it for me (else, reply "unanswerable"): What match degenerated into rioting in July 1990?
Ah, so..
unanswerable
