user: Answer the following question given this paragraph:   An allergy is a disease in which the immune system makes an inflammatory response to a harmless antigen . Any antigen that causes an allergy is called an allergen. Allergens may be inhaled or ingested, or they may come into contact with the skin. Two common causes of allergies are shown in Figure below . Inhaling ragweed pollen may cause coughing and sneezing. Skin contact with oils in poison ivy may cause an itchy rash. Other common causes of allergies include dust mites, mold, animal dander, insect stings, latex, and certain food and medications. Symptoms of a common allergy such as pollen can include sneezing, a runny nose, nasal congestion and itchy, watery eyes.   Q: What is a disease in which the immune system makes an inflammatory response to a harmless antigen?   A:
OPTIONS:
- heartburn
- bronchitis
- cancer
- an allergy

Answer: an allergy

Question: Answer the following question given this paragraph:   In all biomes, ecosystems need a constant input of energy. Matter, on the other hand, is constantly recycled in ecosystems.   Q: While matter is recycled, ecosystems need a constant input of what?   A:
OPTIONS:
- heating
- food
- light
- energy
Answer: energy

input with options: Answer the following question given this paragraph:   Types of friction include static friction, sliding friction, rolling friction, and fluid friction. Fluid friction with air is called air resistance.   Q: What is fluid friction with air called?   A:
OPTIONS:
- buoyancy
- wind resistance
- gravity
- air resistance
output: air resistance

Q: Answer the following question given this paragraph:   Blood Supply The major function of the lungs is to perform gas exchange, which requires blood from the pulmonary circulation. This blood supply contains deoxygenated blood and travels to the lungs where erythrocytes, also known as red blood cells, pick up oxygen to be transported to tissues throughout the body. The pulmonary artery is an artery that arises from the pulmonary trunk and carries deoxygenated, arterial blood to the alveoli. The pulmonary artery branches multiple times as it follows the bronchi, and each branch becomes progressively smaller in diameter. One arteriole and an accompanying venule supply and drain one pulmonary lobule. As they near the alveoli, the pulmonary arteries become the pulmonary capillary network. The pulmonary capillary network consists of tiny vessels with very thin walls that lack smooth muscle fibers. The capillaries branch and follow the bronchioles and structure of the alveoli. It is at this point that the capillary wall meets the alveolar wall, creating the respiratory membrane. Once the blood is oxygenated, it drains from the alveoli by way of multiple pulmonary veins, which exit the lungs through the hilum.   Q: The lungs perform gas exchange using air and what fluid, which is coming and going from the heart?   A:

OPTIONS:
- mucus
- water
- saliva
- blood

A: blood

input: OPTIONS:
- heavy
- gaseous

Question: Answer the following question given this paragraph:   Any two waves in the same medium undergo wave interference as they pass each other. At the location where the two waves collide, the result is essentially a summation of the two waves. In some places, a wave crest from one source will overlap a wave crest from the other source. Since both waves are lifting the medium, the combined wave crest will be twice as high as the original crests. Nearby, a wave trough will overlap another wave trough and the new trough will be twice as deep as the original. This is called constructive interference because the resultant wave is larger than the original waves. Within the interference pattern, the amplitude will be twice the original amplitude. Once the waves pass through each other and are alone again, their amplitudes return to their original values.   Q: What is it called when two waves in the same medium pass one another?   A:
OPTIONS:
- accumulation
- frequency
- synchrony
- interference
Answer:

assistant: interference
