Question: How many years did the Great Depression last? Passage:Originally from New Brunswick, Harrison graduated from Nova Scotia Agricultural College in 1922, and, in 1924, from the Ontario Agricultural College with a B.Sc. in agriculture. He earned an MSc in plant pathology from Macdonald Campus of McGill University a year later. A doctoral degree he started at the University of Toronto in 1929 was abandoned due to the Great Depression. He established a herbarium of mycological specimens where he was employed for many years at the Kentville Research Station (now the Atlantic Food and Horticulture Research Centre); most of his collections are now housed at the Canadian National Mycological Herbarium. His early research concerned the fungal infestation of plants, such as that of Colletotrichum lindemuthianum on beans (Phaseolus). Working with John Frederick DeWitt Hockey, they made many contributions to the control and prevention of diseases of horticultural crops. They were among the first to use the sticky slide spore trap to estimate the densities of fungal spores.

Question: How big is the county that PA 741 begins in? Passage:PA 741 begins at an intersection with PA 722 in the borough of East Petersburg in Lancaster County, heading to the south on two-lane undivided Lemon Street, which is unsigned and locally maintained. The road passes homes prior to crossing into East Hempfield Township, where it becomes Rohrerstown Road and continues through industrial parks. PA 741 gains a center left-turn lane and becomes signed at the Commercial Avenue intersection. The route continues to an interchange with PA 283, at which point it becomes state-maintained. The road crosses the Little Conestoga Creek into Manheim Township after PA 283. The route becomes two lanes again and turns east prior to turning southwest and crossing the Little Conestoga Creek back into East Hempfield Township. At this point, PA 741 becomes McGovernville Road and comes to a bridge over Norfolk Southern's Lititz Secondary and Amtrak's Keystone Corridor. The road passes a mix of homes and woods as it comes to the Harrisburg Pike intersection, where it makes a turn to the south onto Rohrerstown Road, a three lane road with a center left-turn lane. PA 741 passes homes to the west and a branch of Lancaster General Hospital to the east prior to coming to the US 30 interchange. In the area of the interchange, PA 741 is briefly a divided highway. Following US 30, the route becomes a two-lane undivided road and passes residences prior to crossing Norfolk Southern's Columbia Secondary and entering the residential and commercial community of Rohrerstown. Here, PA 741 crosses PA 23. After leaving Rohrerstown, the road passes a mix of farms and businesses prior to an intersection with PA 462.

Question: What was the circulation of Plugged In the year Oops!... I Did It Again was released? Passage:Simpson described Irresistibles material as "Mariah Carey meets Britney Spears ... very mature but accessible to teens." She said that she wanted to blend house, R&B, pop genres into the record. The opening track, "Irresistible", is an R&B song with dance-pop influences. It also exhibits elements of pop rock and funk genres, while incorporating latin rhythms. Aside from including a string section, the track features Simpson's breathy vocals, spoken passages and a mid-section breakdown, where her vocals are "funk-fortified". According to author Ben Graham, the lyrics of the song see Simpson stripping her famous virginity image down. Bob Waliszewski of Plugged In gave a similar observation of the lyrics, writing that they point to an imminent sexual compromise. "A Little Bit" is a dance-pop song following the same beat-oriented pattern as "Irresistible". It features piano instrumentation and Simpson sings the lyrics as rapid-fire verses and with start-and-stop hooks. Simpson again adopts breathy vocals, and the lyrics talk about what she expects from her partner: "A little more time, a little less wait / A little more heart, a little less break". The lyrics also demand healthy changes in her relationship. "Forever In Your Eyes" explores elements of Latin music, as the song is backed by Spanish guitar and infused with hip-hop beats. The lyrics describe a couple in love lying together "all through the night". "There You Were" is a torchy power ballad which drew comparisons to Simpson's previous song "Where You Are" (2000). The lyrics of the song are a homage to the protagonist's partner, who changed her life. The song received negative response from critics, with some calling it "sappy" and "unnecessary". "What's It Gonna Be" is a bubblegum pop song influenced by '80s funk music, which was compared to outtakes from Spears' Oops!... I Did It Again (2000). The lyrics deal with Simpson expecting a reply from her lover regarding his fear of commitment.
