C. Yes, because free’d memory chunks are poisoned.
D. Yes, because free’d memory is unmapped and accesses therefore
cause segmentation faults.

Consider the following CF grammar \(G_1\)
\( R_1: \text{S} \rightarrow \text{NP VP} \)
\( R_2: \text{S} \rightarrow \text{NP VP PNP} \)
\( R_3: \text{PNP} \rightarrow \text{Prep NP} \)
\( R_4: \text{NP} \rightarrow \text{N} \)
\( R_5: \text{NP} \rightarrow \text{Det N} \)
\( R_6: \text{NP} \rightarrow \text{Det N PNP} \)
\( R_7: \text{VP} \rightarrow \text{V} \)
\( R_8: \text{VP} \rightarrow \text{V NP} \)
(where \(\text{Det}\), \(\text{N}\), \(\text{Prep}\) and \(\text{V}\) are the only pre-terminals), complemented by an adequate lexicon \(L_1\).If the sequence \((p_1, p_2, \dots, p_8)\) represents a set of probabilistic coefficients for the syntactic rules in \(G_1\) (\(p_i\) being associated to \(R_i\)), indicate which of the following choices correspond to a valid probabilistic extension for the grammar \(G_1\).
(Penalty for wrong ticks.)
A. (1.00, 0.00, 1.00, 0.00, 1.00, 0.00, 1.00, 0.00)

The following are multiple choice questions (with answers) about knowledge and skills in advanced master-level STEM courses.
Consider a binary classification problem with a linear classifier $f(\mathbf{x})$ given by $$ f(\mathbf{x})= \begin{cases}1, & \mathbf{w}^{\top} \mathbf{x} \geq 0 \\ -1, & \mathbf{w}^{\top} \mathbf{x}<0\end{cases} $$ where $\mathbf{x} \in \mathbb{R}^{3}$. Suppose that the weights of the linear model are equal to $\mathbf{w}=(4,0,-3)$. For the next two questions, we would like to find a minimum-norm adversarial example. Specifically, we are interested in solving the following optimization problem, for a given $\mathbf{x}$ : $$ \min _{\boldsymbol{\delta} \in \mathbb{R}^{3}}\|\boldsymbol{\delta}\|_{2} \quad \text { subject to } \quad \mathbf{w}^{\top}(\mathbf{x}+\boldsymbol{\delta})=0 $$ This leads to the point $\mathbf{x}+\boldsymbol{\delta}$ that lies exactly at the decision boundary and the perturbation $\boldsymbol{\delta}$ is the smallest in terms of the $\ell_{2}$-norm. What is the optimum $\delta^{\star}$ that minimizes the objective in Eq. (OP) for the point $\mathbf{x}=$ $(-1,3,2) ?$
A. $(1,-1,0)$
B. $(0,-1,1)$
C. $(-2,0,0)$
