### Database Schema:
CREATE TABLE Question (
	questiontext	TEXT	NULL,
	questionid	INTEGER	NULL	PRIMARY KEY
);

CREATE TABLE Answer (
	AnswerText	TEXT	NULL,
	SurveyID	INTEGER	NULL,
	UserID	INTEGER	NULL	PRIMARY KEY,
	QuestionID	INTEGER	NULL	PRIMARY KEY,
	foreign key (QuestionID) references Question (questionid),
	foreign key (SurveyID) references Survey (SurveyID)
);

CREATE TABLE Survey (
	SurveyID	INTEGER	NULL	PRIMARY KEY,
	Description	TEXT	NULL
);

### User's Query:
How many respondents who participated in the survey in 2014 work remotely at least 50% of the time?

### Extra Knowledge:
respondents' and 'users' are synonyms; work remotely at least 50% of the time refers to AnswerText(SurveyID = 2014& QuestionID = 93) = 'Yes'
SELECT COUNT(T1.AnswerText) FROM Answer AS T1 INNER JOIN Question AS T2 ON T1.QuestionID = T2.questionid WHERE T1.QuestionID = 93 AND T1.SurveyID = 2014 AND T1.AnswerText = 'Yes'
