В каждом предложении нужно поменять соответствующее указательное местоимение на другое (которое используется с существительными во множественном числе): this - these; that - those
Также нужно было поменять форму глагола 'to be': is/isn't - are/aren't.
Дальше - убрать артикли, так как неопределённый артикль a/an не используется с существительными во множественном числе.
Последнее - поставить существительные в их форму во множественном числе - добавить окончание -s/-es/-ies или как в случае с man, неправильным существительным, поставить его в соответствующую форму.
