You can collect your data, put it in a list, then iterate through the list inside a transaction like so:

private void addAllQuestions(Arraylist allQuestions) {
    SQLiteDatabase db = this.getWritableDatabase();
    db.beginTransaction();
    try {
        ContentValues values = new ContentValues();

        for (Questions question: allQuestions) {
            values.put(QUESTION, question.getQUESTION());
            values.put(OPTION1, question.getOPT1());
            values.put(ANSWER, question.getANSWER());
            values.put(ANSWER2, question.getANSWER2());
            db = this.getWritableDatabase();
            db.insert(TABLE_NAME, null, values);        
        }

        db.setTransactionSuccessful();

    } finally {
        db.endTransaction();
    }
}

public void addquestions() {
    //famous people
    ArrayList allQuestions = new ArrayList();

    allQuestions.append(new Questions("Who was the first African American to have served as president of United States of America ?", "BAROBAACKMAQCAEMBD", "BARACK", "OBAMA"));

    allQuestions.append(new Questions("Who co-founded Apple company with Steve Wozniak, Ronald Wayne ?", "TSOVWIBYUBZRGOEJSE", "STEVE", "JOBS"));

    this.addAllQuestions(allQuestions);
}
