[EX Q]: Context: To investigate whether gender is an independent factor associated with disease expression in early rheumatoid arthritis (RA) patients. 438 patients with early RA (disease duration less than one year) were studied. They all were patients with early RA who presented at the Rheumatology Clinic of the University Hospital of Ioannina during the period 1991-2000. All patients fulfilled the American College of Rheumatology criteria for RA. The demographic, clinical, laboratory, radiological and therapeutic characteristics of the disease at diagnosis, and at the last follow-up were analyzed according to gender. We studied 312 women and 126 men with early RA. The female to male ratio was 2.5:1 and the mean age at diagnosis was 49.4 +/- 14.9 years for women and 55.3 +/-15.6 years for men (P < 0.0003). Women had a longer duration of follow-up (P < 0.0003). There were no differences between genders in the general symptoms or the simmetricity of joint involvement at at disease onset. However at disease onset women had a higher erythrocyte sedimentation rate (ESR) (> 30 mm/1st hour), although there were no significant differences between the two groups concerninig the rest of the clinical, laboratory and radiological findings. At the last follow-up women still had a higher ESR (>30 min/1st hour), but no significant differences were found between the two groups concerning the rest of the parameters investigated independently of the follow-up duration. Finally, women and men showed the same degree of radiological changes and functional ability and were treated similarly except for the more frequent use of hydroxychloroquine in women. It seems that gender does not signficantly influence the expression of RA.

[EX Q]: Context: In 1982, in New Jersey, Gracie (Mary Ashleigh Green) is in a school playground where one boy is bullying another. She steps in and beats up the bully to help the victim, a boy she likes. But instead of being grateful, he feels humiliated at being rescued "by a girl," and gets angry at her. She promptly punches him in the nose and then sulks alone in the playground. Fast-forward to the present day, and Gracie Hart (Sandra Bullock) is an FBI Special Agent. In the middle of an operation against Russian mobsters, the target starts to choke on some food, and Gracie disobeys her superior's command in order to prevent the target from choking. As a result, a member of her squad gets shot, and she is reprimanded by being reassigned to a desk job. Soon afterwards, the bureau learns that there has been a bomb threat against the 75th annual Miss United States beauty pageant in San Antonio, Texas, which the bureau determines came from the notorious domestic terrorist known as "The Citizen". Gracie's partner, Special Agent Eric Matthews (Benjamin Bratt), is chosen to lead the mission to prevent the attack. Despite Eric's position as a lead agent in charge, it is apparent that Gracie is the more capable agent, as Eric is unsure of how to proceed and takes credit for Gracie's suggestions. One of Gracie's suggestions is to put an agent undercover at the pageant. Gracie's male colleagues then proceed to have a bit of fun running the digital images of female and male agents through a website meant for children to play dress up with their dolls. Despite the immature and chauvinistic actions of the agents, Eric recognizes that Gracie is the female FBI agent best qualified for the undercover job. Beauty pageant coach Victor Melling (Michael Caine), whose reputation was ruined after his last contestant criticized his methods, teaches the tomboyish Gracie how to dress, walk, and act like a contestant. She is not used to such behavior, however, and sees the pageant and its participants as "antifeminist ". Eventually though Victor and Gracie come to respect each other's strengths. Representing New Jersey as "Gracie Lou Freebush", Gracie impresses the audience by playing the glass harp and demonstrating self-defense techniques during the talent competition. She also unexpectedly becomes friends with the other contestants, in particular Miss Rhode Island, Cheryl Frasier (Heather Burns) Several suspects emerge, including the corrupt competition director and former pageant winner Kathy Morningside (Candice Bergen); her unpleasant assistant Frank Tobin (Steve Monroe); the veteran pageant MC Stan Fields (William Shatner) who, like Kathy, is being replaced with a younger person; and last but not least Cheryl, who appears to have a history as a radical animal rights activist. While Gracie takes Cheryl and some of the other girls out partying, in an attempt to seek out more information about Cheryl's past through "girl talk", The Citizen is arrested elsewhere on an unrelated charge. After hearing what some of the other contestants said about Kathy Morningside's past (she won the pageant only after the original winner "mysteriously" contracted food poisoning), Gracie begins to suspect her, and is worried about the safety of the girls. Her boss thinks that her suspicions are groundless and that the pageant is out of danger now that the Citizen has been arrested. He calls off the mission. Gracie opts to turn in her badge and gun and continue the investigation alone. Eric initially fails to support Gracie and is about to return to the bureau when he figures out that Gracie's suspicions must be correct, and returns to help her. In the final round of the pageant, Gracie earns 1st Runner up while Cheryl becomes Miss United States. Gracie realizes that Kathy Morningside and Frank Tobin unknown to anyone (except Victor) is Kathy's son impersonated "The Citizen" and made the threat. Because she was going to be fired after the pageant was over, Kathy and her son were planning to murder the newly crowned pageant winner on stage by putting an explosive device in her
