Teacher: Now, understand the problem? Solve this instance: Zimbabwe's President Robert Mugabe has delivered the wrong speech at the opening of a new session of parliament, repeating an address he gave to the legislature last month. 
  
 The 91-year-old leader read the 25-minute-long speech through to the end on Tuesday, apparently unaware that he was delivering the same text he presented during his state of the nation address last month. 
  
 "There has been a mix-up of speeches resulting in a situation where... the president delivered the wrong speech," said presidential spokesman George Charamba. 
  
 "The mix-up happened in his secretarial office," Charamba was quoted as saying in the state-owned Herald newspaper's online edition. 
  
 "The error is sincerely regretted and corrective measures are being considered." 
  
 Mugabe, Africa's oldest leader, earlier this year fell down the steps leading from a podium. He was unhurt, but video of the fall went viral on social media. 
  
 Death threats 
  
 The opening of parliament was also tarnished by claims by opposition legislators that they had received anonymous death threats warning them against booing Mugabe during his address. 
  
 Last month, they booed and heckled him during his state of the nation address in parliament, which is the speech he repeated on Tuesday. 
  
 Movement for Democratic Change (MDC) chief whip Innocent Gonese said seven opposition lawmakers received SMS text messages on their mobile phones warning them not to disrupt Mugabe's address. 
  
 "The message is coming from a number which is not reflecting but it's titled 'death'," Gonese told journalists after Mugabe's speech. 
  
 "It warns the members concerned to know that immunity ends at parliament and once they step out of parliament that parliamentary immunity does not operate." 
  
 Gonese said the party, led by Morgan Tsvangirai, is "worried" about the threats to its lawmakers. ||||| Image copyright AFP Image caption Zanu-PF party supporters clapped at regular intervals during Mr Mugabe's speech 
  
 Zimbabwe's President Robert Mugabe has read out the wrong speech at the opening of parliament. 
  
 He gave the same one during his state-of-the-nation address on 25 August, when he was heckled by opposition MPs. 
  
 His spokesman told the state-run Herald paper the error was because of a mix-up in the president's secretarial office. 
  
 The BBC's Brian Hungwe in Harare says tensions were high ahead of the speech and the state broadcaster cancelled its live feed fearing further disruptions. 
  
 At least six MPs from the opposition Movement for Democratic Change (MDC) received a text message from a sender called "Death" warning them to behave. 
  
 "Warning: Immunity ends in parliament... act wisely by not disturbing the proceedings of parliament," the message on opposition MP Nelson Chamisa's phone said. 
  
 Before the 91-year-old president spoke, the parliamentary speaker also warned against disrupting proceedings. 
  
 After Mr Mugabe began speaking, it was not long before it dawned on those present that they had heard it all before, our reporter says. 
  
 But during the speech, the MDC members sat quietly, while ruling Zanu-PF party supporters clapped at regular intervals, Reuters news agency reports. 
  
 The president made reference to the country amending labour laws to protect workers from arbitrary termination of employment, efforts being made to stimulate investment and the country registering modest growth in tourism and agriculture, our correspondent says. 
  
 The first time Mr Mugabe read the speech opposition MPs sang protest songs against his 10-point plan to solve the country's economic crisis.

 Presidential spokesman George Charamba said the error in delivering the wrong speech was "sincerely regretted". 
  
 He added that the president would read the correct speech later at a hotel in the capital Harare, Reuters reports. ||||| Zimbabwe's President Robert Mugabe gives the speech he intended to make at parliament on Tuesday, at a hotel in the Zimbabwean capital Harare September 15, 2015.

 HARARE Zimbabwe's 91-year-old President Robert Mugabe read out the wrong speech at the opening of parliament on Tuesday, an error which the main opposition quickly used to question whether Africa's oldest leader was still of a sound mind. 
  
 Mugabe, the only ruler the southern African nation has known since it was recognized in 1980, delivered the same speech he gave on Aug. 25, pinning his hopes on China to help revive Zimbabwe's struggling economy. 
  
 Mugabe finished the speech without interruption and his spokesman blamed officials, adding the president would read the correct speech at a later date. 
  
 "The mix-up happened in his secretarial office. Therefore the delivery in Parliament should be set aside," spokesman George Charamba was quoted as saying by the online edition of the government-owned Herald newspaper. 
  
 But the main opposition Movement for Democratic Change (MDC), which is critical of Mugabe's long rule, said the blunder called into question his fitness to hold office. 
  
 Mugabe shows no visible signs of illness and has denied reports that he suffers from prostate cancer. He has dismissed a fall at Harare airport on April. 4 as a simple slip. 
  
 "This is a historic blunder. Anyone who is still of a sound mind would have quickly picked it up that the speech was the wrong one," MDC spokesman Obert Gutu told Reuters. 
  
 "But it dovetails with what we in the MDC have been saying that Robert Mugabe is no longer fit for purpose. He should resign," Gutu said. 
  
 Earlier parliament suspended live television and radio broadcasting of Mugabe's speech after the MDC threatened to disrupt the event. 
  
 The opposition booed and heckled Mugabe about the deteriorating economy during his last speech in August. 
  
 MDC member of parliament Innocent Gonese told parliament that the MDC would disrupt proceedings to protest against anonymous death threats to opposition MPs if they heckled Mugabe again. 
  
 Speaker of parliament Jacob Mudenda, however, warned the MDC they would face contempt charges. Broadcasting was then suspended before Mugabe started his speech. 
  
 During the speech, the MDC members sat quietly, while ruling ZANU-PF party supporters clapped at regular intervals. 
  
 Mugabe arrived at parliament in a vintage black Rolls-Royce car with his wife Grace, and inspected a guard of honor. The 91-year-old leader was also treated to a fly-past by three fighter jets and to a 21-gun salute.

Student:
Robert Mugabe, the 91-year-old president of Zimbabwe, accidentally delivered the wrong 25-minute speech during the opening of the country's parliament today, and no one said anything, Reuters reports. It was the same speech regarding Zimbabwe's struggling economy Mugabe, who's ruled the country since it was recognized 35 years ago, gave during his state of the nation address Aug. 25, according to the BBC. One reporter at the scene says everyone—sans Mugabe apparently—realized it was the wrong speech pretty quickly, but supporters still clapped dutifully. A spokesperson blamed the mixup on the president's secretarial office and said he would deliver the correct speech at a later time. The opposition party, Movement for Democratic Change, is using today's events to bolster claims Mugabe is mentally—and possibly physically—unfit to rule. "This is a historic blunder," an MDC spokesperson tells Reuters. "Anyone who is still of a sound mind would have quickly picked it up that the speech was the wrong one." Mugabe doesn't appear ill and has denied reports he has prostate cancer, but Al Jazeera reports a video of him falling after leaving a podium earlier this year went viral. According to the BBC, MDC officials, who heckled the president during the Aug. 25 delivery of the speech, remained quiet today after receiving what they claim were anonymous death threats warning against further disruptions.
