Read the following paragraph and select the irrelevant sentence.
Physical gestures and body language have different meanings in different cultures, and misunderstanding these signals can sometimes be embarrassing.So we must learn how to tolerate.Although I had spent a lot of time among non-Americans, I had never realized what this could mean in practical terms.I had an experience that taught me well, however.Some years ago, I organized and accompanied a small group of visiting foreign students to New York for four days of sightseeing by bus.Because these students were rather young, and because New York was such an overwhelming city, I was constantly counting heads to be sure we hadn't lost anyone.In the USA , it is very common to count people or things by pointing the index finger and, of course, I used this method.One young man became extremely quiet and pensive, and I thought that perhaps he wasn't enjoying himself.When I asked him what the matter was, he replied, In my country, we count people with our eyes.We use our fingers to count pigs.

After several decades, the same data were 【B11】 to econometric analysis. The Hawthorne experiments had another surprise in store. 【B12】 the descriptions on record, no systematic 【B13】 was found that levels of productivity were related to changes in lighting.

When work started again on Monday, output 【B16】 rose compared with the previous Saturday and 【B17】 to rise for the next couple of days. 【B18】, a comparison with data for weeks when there was no experimentation showed that output always went up on Mondays.

Bacteria (细菌) are extremely small living things. While we measure our own sizes in inches or centimeters, bacterial size is measured in microns. One micron is a thousandth of a millimeter: a pinhead is about a millimeter across. Rod-shaped bacteria are usually from two to four microns long, while rounded ones are generally one micron in diameter. Thus, if you enlarged a rounded bacterium a thousand times, it would be just about the size of a pinhead. An adult human magnified by the same amount would be over a mile (1.6 kilometers) tall.
Even with an ordinary microscope, you must look closely to see bacteria. Using a magnification of 100 times, one finds that bacteria are barely visible as tiny rods or dots. One cannot make out anything of their structure. Using special stains, one can see that some bacteria have attached to them wavy-looking "hairs" called flagella. Others have only one flagellum. The flagella rotate, pushing the bacteria through the water. Many bacteria lack flagella and cannot move about by their own power, while others can glide along over surfaces by some little-understood mechanism.
From the bacterial point of view the world is a very different place from what it is to humans.To a bacterium water is as thick as molasses (糖蜜) is to us. Bacteria are so small that they are influenced by the movements of the chemical molecules around them. Bacteria under the microscope even those with no flagella often bounce about in the water. This is because they collide with the water molecules and are pushed this way and that molecules move so rapidly that within a tenth of a second the molecules around a flagellum have been replaced by new ones. Even bacteria without flagella are thus constantly exposed to a changing environment.
Which of the following is the main topic of the passage？
A．The characteristics of bacteria.
B．How bacteria reproduce.
C．The various functions of bacteria.
D．How bacteria contribute to disease.
