Answer:
a) SQL Query:
SELECT population
FROM bsg_planets
WHERE name='Caprica';
b) SQL Query:
SELECT fname, lname, age
FROM bsg_people
WHERE lname!='Adama';
c) SQL Query:
SELECT name, population
FROM bsg_planets
WHERE population > 2600000000
d) SQL Query:
SELECT fname, lname, age
FROM bsg_people
WHERE age IS NULL;
Explanation:
a) Write a SQL query to find the population of the planet named 'Caprica'
Syntax:
SELECT Column
FROM TableName
WHERE Condition;
For the given case,
Column = population
TableName = bsg_planets
Condition = name='Caprica'
SQL Query:
SELECT population
FROM bsg_planets
WHERE name='Caprica';
Therefore, the above SQL query finds the population of the planet named 'Caprica' from the table bsg_planets.
b) Find the first name, last name, and age of people from bsg_people whose last name is not 'Adama'
Syntax:
SELECT Column1, Column2, Column3
FROM TableName
WHERE Condition;
For the given case,
Column1 = fname
Column2 = lname
Column3 = age
TableName = bsg_people
Condition = lname!='Adama'
SQL Query:
SELECT fname, lname, age
FROM bsg_people
WHERE lname!='Adama';
Therefore, the above SQL query finds the first name, last name and age of people whose last name is not 'Adama' from the table bsg_people.
c) Find the name and population of the planets with a population larger than 2,600,000,000
Syntax:
SELECT Column1, Column2
FROM TableName
WHERE Condition;
For the given case,
Column1 = name
Column2 = population
TableName = bsg_planets
Condition = population > 2600000000
SQL Query:
SELECT name, population
FROM bsg_planets
WHERE population > 2600000000
Therefore, the above SQL query finds the name and population of the planets with a population larger than 2,600,000,000 from the table bsg_planets.
d) Find the first name, last name, and age of people from bsg_people whose age is NULL
Syntax:
SELECT Column1, Column2, Column3
FROM TableName
WHERE Condition;
For the given case,
Column1 = fname
Column2 = lname
Column3 = age
TableName = bsg_people
Condition = age IS NULL
SQL Query:
SELECT fname, lname, age
FROM bsg_people
WHERE age IS NULL;
Therefore, the above SQL query finds the first name, last name and age of people whose age is NULL from the table bsg_people.

Explanation:
The diagrams attached to the questions are shown in the first and the second image below. The first image shows the code and the second image shows the error that appears at the moment of running it.
To answer that ; We will notice that the error in the second image is what it says; what happened is that the individual subject performing this action is trying to to open the file called "h.txt", but the python interpreter is unable to find the file. The individual subject will need to have h.txt inside your current working directory for python to open it.
From the third image attached ; I have careful attached an image that illustrate how you can add the file by going to file → open (right from your jupyter notebook). Afterwards you can either upload the file, or create a new text file and paste the contents on it as displayed in the fourth image attached in the diagram below.
