Please answer this: I have a new situation: Mike is a physician who treats HIV-infected patients. Today, he is seeing two patients, patient A and patient B. Patient A is infected with HIV, but patient B is not infected with HIV. Mike is trying to figure out how HIV-infected patient is different from the patient who is not infected with HIV. But I can use this background: As time passes, the number of HIV copies keeps increasing, while the number of helper T cells keeps decreasing. The graph in Figure below shows how the number of T cells typically declines over a period of many years following the initial HIV infection. As the number of T cells decreases, so does the ability of the immune system to defend the body. As a result, an HIV-infected person develops frequent infections. Medicines can slow down the virus but not get rid of it, so there is no cure at present for HIV infections or AIDS. There also is no vaccine to immunize people against HIV infection, but scientists are working to develop one. What is an answer for this question: Which patient has lower chance of developing infections, patient A or patient B?

Answer: patient B

Please answer this: I have a new situation: Dan is a dance instructor. In an upcoming dance competition he has to send two groups of students, group A and group B. He dressed group A students with godet. But he didn't dress group B students with godet. There are two categories of dance, category C and category D, in the dance competition. Category C requires lots of motion, but category D does not required much motion. Dan has to decide which of his student groups would compete in category C and which group to compete in category D. But I can use this background: A godet (/ode/ or /odt/)[1] is an extra piece of fabric in the shape of a circular sector which is set into a garment, usually a dress or skirt.[2] The addition of a godet causes the article of clothing in question to flare, thus adding width and volume.[3] Adding a godet to a piece of clothing also gives the wearer a wider range of motion.[4] What is an answer for this question: Which group's dress would most probably not flare, group A or group B?

Answer: group B

Please answer this: I have a new situation: Bill and Chris are passionate entomologists. Bill knows everything there is to know about most ants except the Leafcutter ants. Chris studied Leafcutter ants extensively and exclusively for years now. They are good friends and exchange ideas often over a pint of beer. But I can use this background: Most ants are generalist predators, scavengers, and indirect herbivores, but a few have evolved specialised ways of obtaining nutrition. It is believed that many ant species that engage in indirect herbivory rely on specialized symbiosis with their gut microbes to upgrade the nutritional value of the food they collect and allow them to survive in nitrogen poor regions, such as rainforest canopies. Leafcutter ants (Atta and Acromyrmex) feed exclusively on a fungus that grows only within their colonies. They continually collect leaves which are taken to the colony, cut into tiny pieces and placed in fungal gardens. Ergates specialise in related tasks according to their sizes. The largest ants cut stalks, smaller workers chew the leaves and the smallest tend the fungus. Leafcutter ants are sensitive enough to recognise the reaction of the fungus to different plant material, apparently detecting chemical signals from the fungus. If a particular type of leaf is found to be toxic to the fungus, the colony will no longer collect it. The ants feed on structures produced by the fungi called gongylidia. Symbiotic bacteria on the exterior surface of the ants produce antibiotics that kill bacteria introduced into the nest that may harm the fungi. What is an answer for this question: Which friend studied less about fungal gardens?
