Illinois Open, Round 1 wrote:An extraordinary form of this behavior exists in systems for which the double exchange mechanism is energetically favorable, as exemplified by Heusler cells. Two important tools for studying systems with this property are a chart that has the as its x- and y-intercepts the coercivity and remanence, respectively, and a lattice model with Hamiltonian given by the sum over cells of the product of two numbers from U one, one number for the cell and one for each of its neighbors. Materials displaying this property exhibit near-constant H-fields on structures separated by Néel or Bloch walls and known as Weiss domains, which break down at the Curie temperature. For ten points, identify this form of magnetism studied with the aforementioned hysteresis loops and Ising model and materials displaying which retain a permanent magnetization when placed in an external field.
The bolded portion of the question represents how much of it I heard before I buzzed and gave "hysteresis" as the answer. Anyone who knows this material will recognize that the thing being described in the first clause of the second sentence is a hysteresis loop; thus, it was the answer that made sense to me at the time that I buzzed in. Now, some might raise the objection that the first clue uniquely identified ferromagnetism as the correct answer, but this is far from obvious to me; in my research afterwards, I could not turn up anything explicitly referred to as "extraordinary ferromagnetism," so my best guess as to what purpose that adjective serves is that it is a synonym for "unusual," which would make sense because Heusler alloys are alloys that exhibit ferromagnetism even though their constituents do not. Is the same true for hysteresis? It seems that it ought to be, since hysteretic effects are encountered in ferromagnetic materials, though I'm not sure it's exclusive to those materials. In any case, I found the implication that hysteresis loops are used to study ferromagnetism, well, not exactly false, but not really accurate either. It is certainly far less accurate than saying that hysteresis loops are used to study hysteresis, and since I didn't know the first clue at the time, buzzing with that answer on that clue made perfect sense. This is a problem that could have been fixed by saying something like "Materials that exhibit this property also exhibit a behavior that is studied using a chart etc."
T-Party, Editors 1 wrote:Combining observations of these from reactors with prior data from SNO confirms the Large Mixing Angle hypothesis for these. These results from KamLAND improved upon previous measurements of the solar variety of these by Super-K, showing definite flavor oscillation. They make up most of the energy radiated in a supernova, and observations of the 1987A supernova showed that these arrived before the first photons, perhaps resulting from the fact that they are affected only by the weak force. For 10 points, name these particles which come in tau, muon, and electron varieties and which were first postulated by Pauli to allow conservation of energy and momentum in beta decay.
Again, the bolded text is what I heard before buzzing. I gave "neutrino oscillations" as the answer and was negged. I was particularly annoyed by this since this was in our second match against Chicago and they proceeded to 30 the bonus, resulting in a possible 85 point swing in the game had it mattered. In any case, from what I can tell (and perhaps a particle physicist might correct me on this) I am right in my answer at the point where I buzzed. One problem here is that I have no way of knowing what "these" are supposed to be. Certainly neutrino oscillations qualify as "these" things. Another problem is that while "observations" would seem to indicate neutrinos are the right answer (since as I understand flavor oscillations are not "observed" directly, though I suppose "observed" could function here as a generic word meaning "this was the outcome of the experiment") the clue about the mixing angle indicates to me that neutrino oscillations are the correct answer, since the mixing angle is what is introduced to account for oscillations in neutrino flavors. The obvious solution to this problem is to simply say "these particles" instead of just "these" so it would be obvious what the answer should be.
A third example:
T-Party, Playoffs 2 wrote:‘t Hooft-Polyakov monopoles are predicted in these when the second homotopy group of a certain quotient of the underlying gauge group is non-trivial. This group is SU(5) in the Georgi-Glashow model of this, and it must split into the Standard Model gauge under symmetry breaking. It predicts proton decay and gives bounds on the possible masses of the fermions, and indirect evidence for it comes from the fact that the gauge coupling of the electroweak and strong forces seems to have equal strength at around 10 to the 16 GeV, which is known as its namesake scale. For 10 points, name these proposed physical theories that state that the electromagnetic, weak, and strong forces are combined into a single field at extremely high energies.
Answer: _*Grand Unification Theories*_ or _*GUT*_ [accept equivalents containing the word _*unification*_]
While I'm not sure there is anything wrong with the facts of this question, the use of the pronoun "these" and then the pronoun "this" is horribly confusing. In particular, using the word "it" to refer to GUT's in general is strange; from the clue about proton decay I understood that GUTs were being talked about, but I figured the singular pronoun meant a specific GUT was being asked about. Eventually I gave SUSY as the wrong answer, and I have no claim that it should have been accepted, but the formulation of this questions completely threw me off. As I suggested to Andy (and as he apparently implemented afterwards), this question could have been made much less confusing simply by employing a construction like "these statements" (if you don't want to use the word "theory," although the question does just that later on) since that would have made it obvious that what was being sought was a whole class of objects rather than one specific one.
The problem with each of these questions is not so much in the facts themselves as in the fact that they employ indeterminate or inconsistent language in describing the answer that is being sought. It's a problem that I've seen come up now and again and one that is particularly vexing to me in this context since each time I was penalized on topics that I know a fair bit about (I hope no one will say that I don't know ferromagnetism from hysteresis or neutrinos from neutrino oscillations) and I would have been easily able to give the right answer if I had been able to understand what was being asked about. My purpose in writing about this is to encourage people to use specific, definite nouns and pronouns in their questions; those who play on your questions should never have to guess at the answer that is being sought for. On top of that, please pay attention to how your question sounds when it is being read out loud. The moderators at T-Party were generally excellent, but even with Kyle reading, confusion broke out between myself and Eric when the following line was read:
.One of his central findings was challenged on the basis of likely androcentricism in In a Different Voice,
Eric heard that as "one of its central findings" and, buzzing first, said something like "Kohlberg's book... Kohlberg" and kept trying to come up with the title of the book. I heard that as "This central finding," and was buzzing right after Eric with the intent of saying something like "Kohlberg's stages of moral development." (Luckily we got the points anyway). Like I said, even with an excellent moderator like Kyle, you can easily lose one or two key words and be totally thrown off the track, so I think it's preferable to spend the extra characters and write something unambiguous like "This thinker's central findings" or something similar.
In all situations, questions should be written in such a way that they unambiguously identify the correct answer being looked for, not just from a clue accuracy standpoint but from a grammatical standpoint. Whether the answer is a person, location, theory, concept, or whatever, should be obvious to any listener without having to guess what's going on. Most of the questions at both T-Party and IO did not have this problem, but for whatever reason, some of them did, and it's something that I've seen come up in less than meticulously edited tournaments in the past. If in doubt, read the question back to yourself and ask how it would sound or flow if you missed a word somewhere and make sure your description of the answer makes sense.
