The hyphen in the date range '2019-2021' must be replaced with an en dash (U+2013).\n2. The hyphen indicating the negative temperature '-5' must be replaced with a proper minus sign (U+2212).\n3. The two em dashes (U+2014) used for clause separation must be replaced with en dashes (U+2013), with a single space on either side of each en dash.\nAll other text, formatting, and the layout of slide elements must remain unchanged.",
