单选题 The polar lights known as auroras are produced when charged subatomicLine particles, such as protons and electrons flowing from the sun through Earth's magnetosphere, collide with atoms and molecules in Earth's upper atmosphere. For reasons not entirely understood, magnetic storms, called substorms,(5) occasionally occur where the flow of particles greatly increases and the interplanetary magnetic field becomes much stronger. These substorms are frequently visible on the Earth because they increase the intensity of the polar lights. Recently, five identical probes were blasted into orbit in a $200 million US project known as the THEMIS mission. Scientists hope the probes will be able to(10) investigate a number of mysteries about the nature of the substorm instabilities, including when and where substorms begin, how the individual components of the substorm interact, and how substorms power the auroras. The mission's secondary objectives involve understanding and predicting variations in the flux of electrons in Earth's outer radiation belt. These electrons pose a hazard to the(15) safety of both astronauts and spacecraft. Understanding substorm instabilities would thus improve success rates of future space missions.

单选题Traditional critical scholarship has considered a literary work the product of one focused mind, along with its social influences, struggling to achieve self-expression. In such a context, the author's intended meaning, especially as it may be inferred by the circumstances surrounding his life and the work, is extremely important: the author's intention should be taken as the gold standard in determining what constitutes an accurate and valid reading of the text. A natural outgrowth of measuring the validity of readings by this standard is the rejection of those readings that do not fit what the author intended, or what the surrounding culture expected the author to intend.
