Q: If there is more than one light source, there will be several shadows, with the overlapping parts darker, and various combinations of brightnesses or even colors. The more diffuse the lighting is, the softer and more indistinct the shadow outlines become, until they disappear. The lighting of an overcast sky produces few visible shadows.
Can we conclude that can an object have more than one shadow?

The adaptive immune system, also known as the acquired immune system or, more rarely, as the specific immune system, is a subsystem of the overall immune system that is composed of highly specialized, systemic cells and processes that eliminate pathogens or prevent their growth. The acquired immune system is one of the two main immunity strategies found in vertebrates (the other being the innate immune system). Acquired immunity creates immunological memory after an initial response to a specific pathogen, and leads to an enhanced response to subsequent encounters with that pathogen. This process of acquired immunity is the basis of vaccination. Like the innate system, the acquired system includes both humoral immunity components and cell-mediated immunity components.
is adaptive immunity the same as acquired immunity?

Answer: yes
For the eighth and final season (2005--2006), Phoebe takes on the false identity of Julie Bennett (Monica Allgeier) and begins a relationship with an artist named Dex Lawson (Jason Lewis). While under the influence of a spell cast by the prodigy of the Charmed Ones, Billie Jenkins (Kaley Cuoco), Phoebe marries Dex under the alias of Julie. Unsure if she could ever have a lasting marriage with someone she is not completely honest with, Phoebe reveals the truth of her hidden identity to Dex. The pair eventually break up and agree to get an annulment. Phoebe later meets a cupid named Coop (Victor Webster), who was sent by The Elders to help her find love again. When Phoebe discovers that Billie and her sister, Christy (Marnette Patterson) are the ultimate power The Charmed Ones must defeat to save Leo from the Angel of Death (Simon Templeman), she has reservations because the women are human and not demons. In the end, Phoebe participates in the ultimate battle between The Charmed Ones and the Jenkins sisters, which destroys the Halliwell Manor, and only Piper and Billie survive. In the series finale ''Forever Charmed'', Piper uses Coop's time-traveling ring to call upon her mother and grandmother and save Phoebe and Paige. After Christy is defeated, Phoebe and her sisters write about their lives in the Book of Shadows. An epilogue shows Phoebe and Coop getting married and that their marriage will produce three children, all daughters. Phoebe also becomes a successful author, writing a self-help book on finding love.

Problem: Text: Together with the Saint Lawrence Seaway, the Waterway allows both ocean-going vessels and the ore, grain and coal-bearing lake freighters to travel from the system's saltwater outlet to its far interior. The Waterway has larger locks and deeper drafts than the lower Seaway, limiting large freighters to the four lakes upstream of the Welland Canal and Lake Ontario, and similarly restricting passage beyond the canal by larger ocean vessels. The two waterways are often jointly and simply referred to as the ''St. Lawrence Seaway'', since the Great Lakes, together with the St. Lawrence River, comprise a single navigable body of freshwater linking the Atlantic Ocean to the continental interior.

Question: does the great lakes connected to the ocean?

IN: Is it true that do you have to be a citizen of the us to vote?

Since 1996, a federal law has prohibited non-citizens from voting in federal elections, punishing them by fines, imprisonment, inadmissibility, and deportation. Exempt from punishment is any non-citizen who ''reasonably believed at the time of voting (...) that he or she was a citizen of the United States,'' had a parent who is or was a citizen, and began permanently living in the United States before turning 16 years old. The federal law does not prohibit non-citizens from voting in state or local elections, but no state has allowed non-citizens to vote in state elections since Arkansas became the last state to outlaw non-citizen voting in 1926. 11 local governments, 10 of them in Maryland, allow non-citizens to vote in their local elections (Takoma Park, Barnesville, Martin's Additions, Somerset, Chevy Chase Sections 3 and 5, Glen Echo, Garrett Park, Hyattsville, Mount Rainer and Riverdale Park). San Francisco allows noncitizens parents to vote in School Board elections (beginning in 2018).
