A list of the fifteen operas most frequently performed in recent times includes no works by the nineteenth-century German composer Richard Wagner.

Excluding purchases by businesses, the average amount spent on a factory-new car has risen 30 percent in the last five years.

The early universe contained only the lightest elements, hydrogen and helium. Heavier elements, such as carbon, form only in nuclear reactions in stars and are dispersed when the stars explode. A recently discovered gas cloud contained carbon several billion years ago, when the universe was no more than two billion years old.
If the statements above are true, which of the following must, on the basis of them, also be true?
Which of the following, if true, contributes most to an explanation of the change in ice cream sales?
People whose bodies cannot produce the substance cytochrome P450 are three times as likely to develop Parkinson's disease, a disease that affects the brain, as are people whose bodies do produce this substance.

Over a period of several months, researchers attached small lights to the backs of wetas—flightless insects native to New Zealand—enabling researchers for the first time to make comprehensive observations of the insects' nighttime activities.
