Problem: Background: Eleanor Rosalynn Smith was born on August 18, 1927 in Plains, Georgia. She was the eldest of four children of Wilburn Edgar Smith, an auto mechanic and farmer, and Allethea "Allie" Murray Smith, a dressmaker. Her brothers were William Jerrold "Jerry" Smith (1929-2003), an engineer, and Murray Lee Smith (1932-2003), a teacher and minister. Her sister, Lillian Allethea (Smith) Wall (born 1936), is a real estate broker.
Context: When her husband's gubernatorial term ended in January 1975, Rosalynn, Jimmy and Amy Carter returned to Plains. Jimmy had already announced his plans to run for President of the United States. Rosalynn returned to the campaign trail, this time on a national quest to gather support for her husband. She campaigned alone on his behalf in 41 states. Because of her husband's obscurity at the time, she often had to answer the question, "Jimmy who?" She promoted the establishment of additional daycare facilities and adjustments to "Social Security and so many other things to help the elderly."  During the months when she was campaigning across the country, she was elected to the board of directors of the National Association of Mental Health, honored by the National Organization for Women with an Award of Merit for her vigorous support for the Equal Rights Amendment, and received the Volunteer of the Year Award from the Southwestern Association of Volunteer Services.  Rosalynn sat in the balcony at Madison Square Garden with friends and family the night of the nomination while her husband was with his mother and daughter. She had "butterflies in her stomach," until the Ohio delegation announced its votes were for her husband. Rosalynn wished she could have been with him at that time. The Carters met with all the potential running mates, and instantly gained affinity for Walter Mondale after meeting with him and his wife Joan. Following the election, the Carters traveled to the White House and met with President Ford and First Lady Betty Ford, the latter becoming a role model for Rosalynn.
Question: who was the current president?
Answer: the Carters traveled to the White House and met with President Ford and First Lady Betty Ford,

Problem: Background: Raymond Bernard Cattell (20 March 1905 - 2 February 1998) was a British and American psychologist, known for his psychometric research into intrapersonal psychological structure. His work also explored the basic dimensions of personality and temperament, the range of cognitive abilities, the dynamic dimensions of motivation and emotion, the clinical dimensions of abnormal personality, patterns of group syntality and social behavior, applications of personality research to psychotherapy and learning theory, predictors of creativity and achievement, and many multivariate research methods including the refinement of factor analytic methods for exploring and measuring these domains. Cattell authored, co-authored, or edited almost 60 scholarly books, more than 500 research articles, and over 30 standardized psychometric tests, questionnaires, and rating scales. According to a widely cited ranking, Cattell was the 16th most eminent, 7th most cited in the scientific journal literature, and among the most productive, but controversial psychologists of the 20th century.
Context: Cattell noted that in the hard sciences such as chemistry, physics, astronomy, as well as in medical science, unsubstantiated theories were historically widespread until new instruments were developed to improve scientific observation and measurement. In the 1920s, Cattell worked with Charles Spearman who was developing the new statistical technique of factor analysis in his effort to understand the basic dimensions and structure of human abilities. Factor analysis became a powerful tool to help uncover the basic dimensions underlying a confusing array of surface variables within a particular domain.  Factor analysis was built upon the earlier development of the correlation coefficient, which provides a numerical estimate of the degree to which variables are "co-related". For example, if "frequency of exercise" and "blood pressure level" were measured on a large group of people, then intercorrelating these two variables would provide a quantitative estimate of the degree to which "exercise" and "blood pressure" are directly related to each other. Factor analysis performs complex calculations on the correlation coefficients among the variables within a particular domain (such as cognitive ability or personality trait constructs) to determine the basic, unitary factors underlying the particular domain.  While working at the University of London with Spearman exploring the number and nature of human abilities, Cattell postulated that factor analysis could be applied to other areas beyond the domain of abilities. In particular, Cattell was interested in exploring the basic taxonomic dimensions and structure of human personality. He believed that if exploratory factor analysis were applied to a wide range of measures of interpersonal functioning, the basic dimensions within the domain of social behavior could be identified. Thus, factor analysis could be used to discover the fundamental dimensions underlying the large number of surface behaviors, thereby facilitating more effective research.  As noted above, Cattell made many important innovative contributions to factor analytic methodology, including the Scree Test to estimate the optimal number of factors to extract, the "Procrustes" oblique rotation strategy, the Coefficient of Profile Similarity, P-technique factor analysis, dR-technique factor analysis, the Taxonome program, as well the Rotoplot program for attaining maximum simple structure solutions. In addition, many eminent researchers received their grounding in factor analytic methodology under the guidance of Cattell, including Richard Gorsuch, an authority on exploratory factor analytic methods.
Question: What will it provide?
Answer:
then intercorrelating these two variables would provide a quantitative estimate of the degree to which "exercise" and "blood pressure" are directly related to each other.
