Extract:

Omega-3 fatty acids include alpha-linolenic acid (ALA), docosahexaenoic acid (DHA), and eicosapentaenoic acid (EPA). Your body needs omega-3s; they appear in the membranes that surround every cell in your body. Some people take omega-3 supplements such as cod liver oil, but with a little dietary care, you should be able to obtain adequate omega-3s from your daily nutrition. ALA is available in plant-based oils, especially flaxseed and canola oils. Some leafy greens, wheat germ, and walnuts also contain ALA. DHA and EPA occur naturally in fatty fish such as tuna, mackerel, sardines, bluefish, and salmon. Vegetarians may obtain some DHA and EPA from algal sources.
The positive effects on health of a diet rich in omega-3s are clear, although further research is needed to know exactly how omega-3s help. They seem to reduce inflammation, lower blood pressure, and reduce the buildup of plaque in the arteries, making them critical in maintaining heart health. Researchers have found that people with a high omega-3 intake seem to have fewer colon and breast cancers. Because of the fatty acids’ effect on inflammation, some doctors find omega-3 supplements useful for asthma and arthritis patients.
Less clear are the effects on mental health, although there are health professionals who believe strongly that high levels of omega-3s can reduce depression, improve memory, and moderate symptoms of attention deficit hyperactive disorder. Until more research takes place, it is unwise to rely on omega-3s to cure mental health issues. However, ensuring that your diet contains ample amounts of these critical fatty acids is still a good idea.

Extract:

In California, three paint manufacturers recently settled a 19-year lawsuit for $305 million. Their crime (to which they did not admit) was marketing lead paint while knowing its toxicity. It was a surprising ending for many who believed that because the companies sold the paint prior to the government ban on its use, they could not be held liable for its harmful effects years afterward. The money will be used by municipalities to mitigate lead hazards in older homes, inspecting, evaluating, and removing paint where warranted. The funds are expected to be quickly depleted; there are thousands of such houses, and each could cost over $1,000 to remediate.
Even small amounts of lead in the body can result in serious health problems, but the symptoms are often difficult to associate with lead. In young children, lead exposure can cause brain damage leading to developmental delays, seizures, fatigue, or irritability. Adults may experience high blood pressure, muscle pain, or memory loss. Pregnant women exposed to lead over time are prone to miscarriages and stillbirths.
Although lead paint has been banned in the United States since 1978, and U.S. manufacturers stopped using lead-soldered cans in 1991, older buildings still have lead pipes, and lead may appear in bullets or batteries as well as in some pottery and toys made overseas. A major lead disaster occurred in 2015 when tests indicated dangerous lead levels in residents’ water in Flint, Michigan. In that case, lead leached from the water pipes when the state failed to treat the water with an anticorrosive agent. It took months for the city to declare a state of emergency, during which time thousands of children and adults had been poisoned.

HEAT EXHAUSTION:
One of the human effects of the climate crisis is that as temperatures climb, more and more people are in danger of heat exhaustion. A recent spate of triple-digit temperatures occurred in states where such temperatures are rare. Municipalities provided cooling centers, which doubtless saved some lives. Knowing the signs of heat exhaustion can help you protect yourself on the hottest of days. Left untreated, heat exhaustion may lead to heatstroke, which can be fatal.
If you are forced to be outside and active in a place where high temperatures combine with high humidity, monitor your body for unusual reactions. People with heat exhaustion may sweat heavily yet have skin that feels clammy or cold. They may have a sudden sharp headache or muscle cramps and experience dizziness when standing up, which can lead to nausea. If you notice that your heart is racing and you feel faint, stop your activity at once. Find a cool place to rest, and hydrate immediately with water or an electrolyte-fortified sports drink.
If you suddenly stop sweating entirely, become confused, or cannot drink, you need immediate medical attention. Be aware that certain medical conditions—such as obesity or any condition that requires you to take beta blockers, tranquilizers, or antipsychotics—may exacerbate your reaction to excessive heat. If your weight or medications make you susceptible to heat exhaustion, avoid all physical activity when the heat index is over 90 degrees.

Which conclusion can the reader draw after reading this passage?

Correct Answer: C

Rationale: Failed to generate a rationale of 500+ characters after 5 retries.

Extract:

Microsurgery as we know it today was developed in Sweden in the 1920s for use on animals. The first microsurgery used a monocular microscope, but soon a Swedish doctor developed a surgical binocular microscope, which became widely used in delicate ear operations. It was not until the 1960s that microscopy was first used to augment neurovascular surgery. Surgeons found that with the help of the microscope, they could repair the tiniest of blood vessels and even reconstruct vessels in partially amputated limbs.
In that same decade, a German surgeon developed the diploscope, which consisted of two independent binocular microscopes. This innovation allowed a surgeon to use high magnification while a surgical assistant followed along at a lower magnification, thereby observing a larger area of operation and addressing potential issues more effectively. This improvement in microscopy led to advances in plastic surgery, an area of medicine that regularly requires work on the tiniest of blood vessels and nerves.
Technological advances have continued to expand the possibilities of microsurgery. Surgeons can now perform procedures on cerebral aneurysms, reverse vasectomies, and improve breast reconstruction after cancer surgery. New tools such as telerobotic arms connected to microsurgical forceps and video microscopy, where the operative field is displayed in high definition on a TV monitor, have made even the most complex surgeries routine.


Question 5 of 5

The passage mentions all of these uses for microscopy EXCEPT ___________.

Correct Answer: C

Rationale: The correct answer is C. The passage discusses various uses of microscopy in surgery, including ear surgery, amputations, and reconstructions. However, vasectomies are not mentioned as an application of microscopy in the text.
Therefore, vasectomies are the exception among the listed uses.

Choices A, B, and D are supported by details in the extract, making them incorrect answers. The passage highlights the uses of microscopy in delicate ear operations, repairing blood vessels in partially amputated limbs, and improving breast reconstructions. While vasectomies are mentioned briefly in the extract, they are not connected to the application of microscopy in the context of surgeries.
