The obvious element for which it can't exist is 0 as a*0=0 independent of modulo
all other elements have an inverse:
1*1≡1
2*3≡6≡1
3*2≡6≡1
4*4≡16≡1
if there are more than a few numbers/guessing is inefficient it can be calculated using the extended euclidean algorithm

Answer:
We can optimize our search in the following manner:
1. Type "From greenhouse to icehouse: The marine Eocene-Oligocene transition" in the search box
2. Search in the " Title" field
The same approach can be used in any library, with just the diffence of its syntax, some libraries might provide up-front checkbox options to select in which field (title, text, author, publisher etc) one wants to search in, while in others one have to use specific commands.
For instance, if we use the advance search in google we can write the following.
<em>allintext:"From greenhouse to icehouse: The marine Eocene-Oligocene transition"</em>
<em></em>

Answer:
b. mkdir -p ~/2019projects/project/projectplans
Explanation:
mkdir command in Linux environment is used to create a new directory. This command is used to create a folder to store the information in organized manners.
-p is used to create a parent folder in the directory. If we want to start a new project or want to store information about some new topic we will create a new folder for that purpose. So, -p is used to create a new folder in directory.
In above mentioned case, this is the first project that Mindy started in 2019, so she should create a parent directory of 2019 to save all projects details that she worked in 2019. So she should use -p with mkdir command to make 2019 as a parent folder.
