Q #1: What is all this talk of cicadas lately in the United States? You might be wondering why the media has featured it, but in fact, the discussion about cicadas has emerged about as predictably as the cicadas themselves from their underground refuge. Let's get oriented with some background on cicadas. What is a cicada? A typical definition will at least tell you that the cicada is a large, loud insect with long transparent wings, mostly found in warm countries. A more detailed response might also inform you that cicadas have short antennae and wide-set eyes that jut out, with delicate, translucent wings and that not only is the cicada loud, but few creatures make a louder sound. In fact, it is male cicadas that are the noisy ones, to the tune of 80 to 100 decibels, which is like the roar of a loud engine. This is because male cicadas make a strident, high buzzing by vibrating two membranes on its abdomen called tymbals, effectively turning its body into a kind of echo chamber or drum, Female cicadas cannot replicate the buzzing, though they respond with a clicking sound when they are ready to mate. Although there are several species of cicada, mating typically takes place in trees whereafter the female deposits the eggs into the bark. Wher the eggs hatch, the larval cicadas, called nymphs, drop to the ground and burrow. They then live as nymphs for most of their lives over 6 feet underground, with both male and female cicadas dying within weeks of their emergence from the soil. This is particularly true for North American cicadas, especially the Magicicodo, or periodical cicadas, which regularly emerge in intervals of 13 or 17 years, depending on the species and the location. This is why talk of cicadas in the media is as predictable as their emergence in the US. Which of the following words does the author use to express a derogatory tone?

A. Noisy

B. Roar

C. Delicate

D. Predictable

Answer Explanation

This term is used in a negative context to describe the male cicadas' loud buzzing, suggesting a critical or disapproving attitude towards this aspect of cicadas.
