Article: On July 11, 1877, a few days after the Bell Telephone Company was established, Bell married Mabel Hubbard (18571923) at the Hubbard estate in Cambridge, Massachusetts. His wedding present to his bride was to turn over 1,487 of his 1,497 shares in the newly formed Bell Telephone Company. Shortly thereafter, the newlyweds embarked on a year-long honeymoon in Europe. During that excursion, Bell took a handmade model of his telephone with him, making it a "working holiday". The courtship had begun years earlier; however, Bell waited until he was more financially secure before marrying. Although the telephone appeared to be an "instant" success, it was not initially a profitable venture and Bell's main sources of income were from lectures until after 1897. One unusual request exacted by his fiancee was that he use "Alec" rather than the family's earlier familiar name of "Aleck". From 1876, he would sign his name "Alec Bell". They had four children:

Here is a question about this article: Shift-work or chronic jet-lag have profound consequences on circadian and metabolic events in the body. Animals that are forced to eat during their resting period show increased body mass and altered expression of clock and metabolic genes.[medical citation needed] In humans, shift-work that favors irregular eating times is associated with altered insulin sensitivity and higher body mass. Shift-work also leads to increased metabolic risks for cardio-metabolic syndrome, hypertension, inflammation.
What is the answer to this question: What type of work can lead to heart, hypertension and inflammation?
****
So... Shift-work

The problem: Answer a question about this article:
Britain retains sovereignty over 14 territories outside the British Isles, which were renamed the British Overseas Territories in 2002. Some are uninhabited except for transient military or scientific personnel; the remainder are self-governing to varying degrees and are reliant on the UK for foreign relations and defence. The British government has stated its willingness to assist any Overseas Territory that wishes to proceed to independence, where that is an option. British sovereignty of several of the overseas territories is disputed by their geographical neighbours: Gibraltar is claimed by Spain, the Falkland Islands and South Georgia and the South Sandwich Islands are claimed by Argentina, and the British Indian Ocean Territory is claimed by Mauritius and Seychelles. The British Antarctic Territory is subject to overlapping claims by Argentina and Chile, while many countries do not recognise any territorial claims in Antarctica.
Which country besides Britain claims the South Sandwich Islands?
****
The answer: Argentina

Problem: Please answer a question about the following article about Mammal:
Viviparous mammals are in the subclass Theria; those living today are in the marsupial and placental infraclasses. A marsupial has a short gestation period, typically shorter than its estrous cycle, and gives birth to an undeveloped newborn that then undergoes further development; in many species, this takes place within a pouch-like sac, the marsupium, located in the front of the mother's abdomen. This is the plesyomorphic condition among viviparous mammals; the presence of epipubic bones in all non-placental mammals prevents the expansion of the torso needed for full pregnancy. Even non-placental eutherians probably reproduced this way.
What is present in all non-placental mammals?
A: epipubic bones

Since chlorinated hydrocarbon pesticides dissolve in fats and are not excreted, organisms tend to retain them almost indefinitely. Biological magnification is the process whereby these chlorinated hydrocarbons (pesticides) are more concentrated at each level of the food chain. Among marine animals, pesticide concentrations are higher in carnivorous fishes, and even more so in the fish-eating birds and mammals at the top of the ecological pyramid. Global distillation is the process whereby pesticides are transported from warmer to colder regions of the Earth, in particular the Poles and mountain tops. Pesticides that evaporate into the atmosphere at relatively high temperature can be carried considerable distances (thousands of kilometers) by the wind to an area of lower temperature, where they condense and are carried back to the ground in rain or snow.

Why are hydrocarbon pesticides not excreted?
Answer: dissolve in fats

The Paris department store had its roots in the magasin de nouveautes, or novelty store; the first, the Tapis Rouge, was created in 1784. They flourished in the early 19th century, with La Belle Jardiniere (1824), Aux Trois Quartiers (1829), and Le Petit Saint Thomas (1830). Balzac described their functioning in his novel Cesar Birotteau. In the 1840s, with the arrival of the railroads in Paris and the increased number of shoppers they brought, they grew in size, and began to have large plate glass display windows, fixed prices and price tags, and advertising in newspapers.
What factors influenced the increase of department stores in Paris?
the arrival of the railroads in Paris and the increased number of shoppers they brought
