Q: Fill a measuring cup with 1 cup (237 ml) of whole milk minus 1 to 2 tablespoons (15 to 30 ml). Next, add 1 tablespoon (15 ml) of fresh lemon juice or white vinegar to the milk. You can substitute 2% milk or heavy cream for the whole milk if you prefer. After you’ve added the lemon juice or vinegar to the milk, use a spoon to mix the two together. Be sure to blend them well so the acid is fully incorporated into the milk. Once the milk and acid have been mixed together completely, allow the mixture to stand at room temperature for 5 to 10 minutes. That will give it time to thicken up and curdle slightly so you’ll have sour milk. The recipe makes 1 cup (237 cup) of sour milk. However, you can easily halve, double, or triple it based on your needs.
A: Pour the acid into the milk. Stir the acid and milk together well. Let the milk mixture sit for at least 5 minutes.

Article: Typhoid fever is a serious and potentially life-threatening infection if treatment is not received promptly. Therefore, if you suspect you may have it, it is important to be evaluated by a medical professional as soon as possible.  Start by seeing your family doctor who can refer you on to an infectious disease specialist. However, if you are unable to get a same-day appointment with your family doctor, you may proceed directly to the emergency room for the fastest evaluation and treatment.  Your doctor will ask you for a travel history, as places to which you have travelled is a key factor in diagnosing typhoid fever. Typhoid fever is most commonly caused by the bacteria "Salmonella typhi." Humans are carriers of the disease, and it is passed on via fecal-oral transmission. What this means is that fecal remnants get on someone's hands, and then they touch food or water, which is subsequently ingested by another who then becomes infected with the disease.  People can also become carriers of the disease, without necessarily knowing it, and this can contribute to disease outbreaks.  Typhoid fever is most prominent in under-developed countries, where hand hygiene is less enforced. The illness usually takes about 1-2 weeks to present with symptoms after it has entered your system (so there is a delay post exposure). Once symptoms begin to appear, they typically last 3-4 weeks and then remit if appropriate medical treatment is administered. Common signs and symptoms include:  A fever which gradually worsens (up to 104 degrees Fahrenheit) Poor appetite Fatigue Bowel disturbances (diarrhea or constipation) Headaches Often abdominal pain and discomfort Sometimes chest congestion Note that, even after treatment, 10% of people have a relapse of symptoms. Therefore, always be on the watch for these symptoms if you suspect you may have typhoid fever, or may be developing a relapse. If you have typhoid fever, the following tests can be used to aid in diagnosis:  A stool test can look for the presence of "Salmonella typhi" bacteria in your stool. Since the bacteria initially enter your body via the gastrointestinal tract, it can often first be detected in the stool.  If a stool test is inconclusive, your doctor will likely proceed to blood tests. The infection quickly spreads from the GI tract to various other parts of the body, so can be most often be detected in the blood as well. If a stool test and/or a blood test is insufficient to confirm a diagnosis of typhoid fever, your doctor may proceed with a urine analysis or bone marrow test. Both of these methods can also be successful at diagnosing typhoid fever, since it tends to be widespread throughout the body. A bone marrow test is more complicated to conduct, but it is also the most precise method to confirm the presence of the "Salmonella typhi" bacteria in your body. If typhoid fever is confirmed, it is generally treated with antibiotics. Cipro and Rocephin are the two most commonly prescribed antibiotics for typhoid fever. Take the antibiotics as directed by your physician. Prior to the use of antibiotics, about 20% of people died of typhoid fever. It can be a very serious illness, and this is why prompt medical evaluation and following through with treatment are key.
Question: What is a summary of what this article is about?
Seek medical attention promptly. Understand what typhoid fever is and how it is transmitted. Recognize signs and symptoms of typhoid fever. Undergo diagnostic tests by your doctor. Learn about other methods of diagnosis. Follow through with treatment.

Q: The reason questions are a successful sales tactic is that they allow the customer to do most of the talking. This gives you a better idea of what their needs are and how you can sell your product to them. But this only works if you actually give your customer time to talk. In other words, don't drown them in product description and technical information. Instead, save this information for later, when you've identified the problem and already sold them on the fact that you can provide a solution. After all, if they just wanted information, odds are they could get it on your website. You need to figure out exactly what you could bring to your prospect and how what you bring can further their overall goals. You already have the first part from your discussions of the customer's problem. However, for the second part you will need an idea of what the customer wants to achieve overall. Try coming at this directly with something like, "What are you looking to accomplish in the next few years?" or "What is the primary long-term goal of your business?". From here, you can tailor the language and content of your product or service offering to how you can help them along the path to achieving their goals. You can also draw out customer desires by asking them to imagine the future of their business or life. You can either ask about how their life or business will be in the future or how they hope your business relationship will develop. For example, try asking, "Where do you see yourself/your company in five years? Ten years?" or, "How do you see your business developing if we go through with this deal?". You can gather even more information by asking other hypothetical questions like, "If you had no monetary constraints, what changes would you make?". Listen to these responses and think about the solutions you could provide. At regular intervals, especially if you are explaining something complex, stop to ask your customer if they have any questions. This not only keeps them engaged, but can keep you from having to go back and explain something you've already moved past. In any case, try to maintain an air of helpfulness and take the time to explain anything the customer doesn't understand, as well as to understand their concerns as deeply as possible. And when your customer is thinking about their answers or questions, wait patiently and quietly.
A:
Let the customer talk. Inquire about their overall goals. Ask about the future. Find out if they have any questions.
