想請教一下第一題 感覺C也蠻合理的… 非常感謝!

三、篇章結構 New Year's Eve is celebrated in every corner of the globe, but there is nowhere more popular or more famous for its New Year's Eve celebration than New York's 21 Times Square. Hundreds of millions of people around the world are at that moment united as they bid a fond farewell to the year just past, and greet the New Year with their optimistic hopes and dreams. 22 The actual square is located in the center of New York City, where Broadway and 7th Avenue intersect with West 46th Street, just a few blocks south of Central Park. The whole Times Square district takes in several more blocks from 42nd Street to 47th Street. 23 The site of the original Times building is actually where the New Years Eve ball drop is now located. The crossroads of the world is also an apt description of how culture, art, business, media, and every other part of society all seem to merge in this uniquely diverse neighborhood. Surprisingly, Times Square's biggest claim to fame is that it is the world's most popular tourist destination. Over 300,000 tourists visit the district daily, which equates With more neon billboards than Las Vegas, to 39 million people annually. 24 more theatres than London's West End, and more restaurants than Paris, maybe it's not that surprising.

Experiment 7 Experiment 7 The partition of Organic acid between Water and Organic solvent Objectives Understand the partition of a solute between two immiscible solvents. Introduction A chemical analysis that is performed primarily with the aid of volumetric glassware (e.g., pipets, burets, volumetric flasks) is called a volumetric analysis. For a volumetric analysis procedure, a known quantity or a carefully measured amount of one substance reacts with a to-be-determined amount of another substance with the reaction occurring in aqueous solution. The volumes of all solutions are carefully measured with volumetric glassware. The known amount of the substance for an analysis is generally measured and available in two ways: 1. As a primary standard: An accurate mass (and thus, moles) of a solid substance is measured on a balance, dissolved in water, and then reacted with the substance being analyzed. 2. As a standard solution: A measured number of moles of substance is present in a measured volume of solution - a solution of known concentration, generally expressed as the molar concentration (or molarity) of the substance. A measured volume of the standard solution then reacts with the substance being analyzed. The reaction of the known substance with the substance to be analyzed, occurring in aqueous solution, is generally conducted by a titration procedure. The titration procedure required a buret to dispense a liquid, called the titrant, into a flask containing the analyte. A reaction is complete when stoichiometric amounts of the reacting substances are combined. In a titration this is the stoichiometric point. In this experiment the stoichiometric point for the acid-base titration is detected using a phenolphthalein indicator. Phenolphthalein is colorless in an acidic solution but pink in a basic solution. The point in the titration at which the phenolphthalein changes color is called the endpoint of the indicator. Indicators are selected so that the stoichiometric point in the titration coincides (at approximately the same pH) with the endpoint of the indicator.

請問第49題,為什麼F選項也可以選啊?我覺得Linda是可以接受,只是說希望價格降低。 應該是要價格降低才會買的情況,這題才能選F吧?

第貳部分、混合題(占10分) 說明:本部分共有1題組,每一題配分標題末。限在答題卷標示題號的作答區內作答, 並以規定用筆作答。 Even if you're not a vegetarian, there's a good chance you've heard of plant-based meat. These meat substitutes are often advertised as beneficial for the environment. But do the customers really like them? Read the following chatroom discussions about GreenBurger, a product using alternative-meat patties. (A) Olivia That's a firm NO! I tried one when I was a prep cook for Next Level Burgers...tasted awful, just like mashed peas gone to rot. (B) Smith I haven't tried them. I just don't see the point. They are heavily processed with more calories and sodium than meat and are more expensive too! Unless you are a strict vegetarian and eschew meat for ethical reasons, meat is surely a better deal. (C) Mika Not really. It tastes too much like actual meat. If I wanted to eat a dead cow, I would go for real burgers. Being vegan means I try to stick to plant food. But this is just not something that will ever interest me. (D) Thomas GreenBurger just tastes "beany" to me, so I think that whatever form it comes in, it works better in recipes that would usually contain beans, such as in a rice bowl (as ground meat substitute). That being said, I'm definitely a carnivore and prefer meat, but I don't see anything wrong with choosing one of the fakey- fakey meaty things once in a while-just for a change. (E) Rico I finally tried one last week. It didn't taste that bad, but I was surprised to find it had 40 more calories than the meat version! Isn't it supposed to be a healthy choice? (F) Linda I liked it fine. I did NOT like the price, though. Hopefully that will come down. I'm trying to eat less beef. (G) Ablo Yes! My whole family does. We've been mostly vegan 90% of the time for the last 6 years and we cannot thank GreenBurger enough! Especially when a burger craving hits...a GreenBurger does the trick. I've tried all kinds of vegan "burgers," and GreenBurgers are closer to what I'm looking for. In fact, I can have them every day-vegan or not! (H) Alexander Well, they taste good if you add plenty of spices and sauces. Good for you? No, not at all. They're highly processed and contain no vegetables. They also contain a very large amount of processed coconut oil, which is even worse than lard. It's a killer for sure if eaten regularly.
